filed Dec. 19, 2000 by the same inventors, and claims priority
therefrom.
FIELD OF THE INVENTION
[0002] The present invention is directed to a method for informing
a user of the status and characteristics of a product such as a
consumable product. More specifically, the present invention is
directed to a method for notifying a user, via a printing
operation, that a customer replaceable unit (CRU) should be
reordered. The method provides ready accessibility to a variety of
information to aid the user in purchasing a replacement cartridge,
bottle, printhead, or photoreceptor.

of which are totally incorporated herein by reference.
[0004] A user may be informed when a marking material in a CRU is
at a level too low to confidently print any further jobs. Once a
user is signaled of a problem, a further problem is that, at a time
of recognized need, the user may not have the necessary information
readily in their possession in order to make a decision with
respect to a replacement CRU. For example, the user may not possess
the manufacturer's recommended CRU replacement model, the user may
not know where to order the CRU, the user may not have the CRU
manufacturer or vendor(s) contact information, the user may not
know how to remove and recycle the CRU, or the user may not know
how to install the replacement CRU. Such beneficial information is
most useful when a user is notified that a CRU will soon run out of
a substance or when the CRU is at or near the end of its useful
life.
[0005] In view of these problems, the present invention proposes a
method and system which provides a user with various useful
information concerning the CRU in the form of a printed document.
The method and system makes the CRU information available to the
user at the source of the problem, and at an identified time of
need in the printing machine. The information is provided in one
convenient place, in the form of a printed document.

BRIEF DESCRIPTION OF THE DRAWINGS
[0015] FIG. 1 is a flowchart illustrating a process carried out by
a system of the present invention; and
[0016] FIG. 2 is an extension of the flowchart of FIG. 1
illustrating a further process carried out by a system of the
present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0017] The present invention relates to embodiments of a method and
system for aiding a user in recognition of a problem in the CRU(s)
and for providing the user with a printed document including
information to solve the problem. While the principles of the
present invention will be described in connection with a printing
machine, copying machine, or combination thereof, such as an
electrostatographic machine, it should be understood that the
present invention is not limited to that embodiment or to that
application. Therefore, it is should be understood that the
principles of the present invention extend to all alternatives,
modifications, and equivalents as may be included within the spirit
and scope of the appended claims.
[0018] In operation, as an indication is made that a new CRU should
be ordered based on, for example, events, image count, pixel count,
or sensors, a machine prints a document with predetermined
information about the CRU for the user to use. In addition, the
document can be sent electronically to the user at a personal
computer.
[0019] A printing or copying machine may comprise replaceable
CRU(s) such as a photoreceptor cartridge, a developer cartridge, a
toner cartridge, an ink cartridge, printhead, and print cartridge
each of which is generally designed to function for a preset number
of images in the form of prints or copies. The photoreceptor
cartridge includes a photoreceptor drum. The developer cartridge
includes a development system and receives a toner cartridge. The
toner cartridge includes a sump for toner. The ink cartridge
includes ink. The print cartridge may include at least one ink
container fluidly connected to at least one printhead. The
printhead ejects ink onto a print medium such as paper in
controlled patterns of closely spaced dots. The printhead may be
sealingly attached to the ink container and the combined printhead
and container form a cartridge.
[0020] Each CRU includes a memory device such as a customer
replaceable unit monitor (CRUM) integral therewith. Each CRUM may
include multiple memories of different types. To enable the CRUM to
be electrically connected and disconnected with the printing
machine on installation or removal of the CRU, contact pads are
provided. Terminal blocks and a terminal board may be used to
complete the electrical connection between the CRUM and a control
unit of the printing machine.
[0021] Various electronic memory systems may be used in the CRUM
including ROM, RAM, EEPROM, magnetic, or optical. Data relating to
the CRU may be stored in a memory on the CRUM. For example, a
preset number of total images for the CRU, various threshold(s)
values of use for notice for the CRU, and various predetermined
information to aid the user may be programmed into the CRUM by the
manufacturer. The CRUM may include addressable memory for storing
various information about the CRU. The CRUM may have a number of
programmed thresholds ranging from one to several hundred, although
less than ten thresholds, such as one to five thresholds for the
CRU are envisioned. The thresholds for the CRU may be set at
various values. In addition, the CRUM may be updated, for example,
with a count of events in which the CRU has functioned in by the
control unit of the printing machine at the end of each run. For
example, each CRUM may be pre-programmed with total images value
reflecting the maximum number of images that can be made using the
CRU. The total images value may decline as each image is made to
provide a current total image count value.
[0022] The control unit of the printing machine may include
microprocessors and suitable memory, such as Read Only Memory (ROM)
and Random Access Memory (RAM) for holding, for example, the
operating system software of the printing machine and programming
data for operating the various component parts of the printing
machine in an integrated fashion to produce prints/copies.
[0023] In operation, when the number of remaining images in the CRU
reaches a predetermined programmed level, predetermined information
about the CRU from the CRUM may be provided in a printed document
at the printing machine to aid the user. For example, the
predetermined information about the CRU may relate to obtaining,
ordering, using, removing, installing, recycling, or combinations
thereof. The system is intended to provide sufficient notice of the
demise of the CRU at various intervals of use and to allow the user
sufficient time, for example, about two weeks to order a
replacement CRU using the information readily provided in the
printed document. The predetermined information allows the user to
solve a problem with respect to the CRU during the life of the CRU.
In addition, an electronic e-mail message may be sent to the user,
to a User Interface (UI), or to a display window to supplement the
printed document.
[0024] The notice based on the remaining images with respect to the
CRU may be provided at selected intervals or at selected thresholds
based on, for example: a percentage of life remaining in the CRU,
ranging from 100% to 0%; a number of images remaining for the CRU
to function, ranging from about fifty thousand remaining images to
one remaining image; and a number of weeks for the CRU to function,
ranging from about sixteen weeks to about one week, depending on
the users anticipated or average monthly image volume.
[0025] After the notice has been provided in a printed document,
the printing machine may continue to make the remaining images
until a final threshold value is reached in the CRU indicating the
CRU is at its end of life. Then, the printing machine may print end
of life documents including various predetermined information.
Shortly thereafter, the CRU or printing machine is then inoperable.
The old CRU must then be removed and replaced by a replacement CRU
in order for further operation of the printing machine.
[0026] In operation, when the print/copy run process is completed
and the printing machine cycles down, the total number of images
made during the run may be temporarily stored in a memory of the
printing machine. The control unit of the printing machine may read
the current image total from the CRUM of each CRU and, using the
image run count from the memory of the printing machine, calculate
a new current image total for the respective CRUM reflecting the
number of images remaining on the CRU. The control unit may then
write the new current image total back into the CRUM of each
CRU.
[0027] The control unit may then compare each new current image
total against the remaining images for the CRU and upon the
comparison reaching a threshold value, a printed notice including
the predetermined information may be printed at the printing
machine for the particular CRU. This notification provides useful
information about the CRU and may alert the user to the fact that
the identified CRU is about to expire and that a new replacement
CRU should be made available and installed soon in the printing
machine.
[0028] Turning now to FIG. 1, illustrated is a process in a system
that starts at S10 with a machine that is ready to print/copy.
Next, at S20, the `print/copy start signal` is received at the
machine. At S30, the running of the printing/copying process begins
at the machine.
[0029] At S100, the actual value of the use of the CRU recorded by
the machine, such as the number of copies, prints, cycles, or other
events involving the CRU, is compared to a first threshold value
programmed on the CRUM to determine if the CRU use is greater than
or equal to the first threshold value for the CRU. For CRU use that
is less than the first threshold value programmed on the CRUM, the
machine will return to the ready state. For a value greater than or
equal to the first threshold value programmed on the CRUM, S200 is
entered.
[0030] At S200, the machine software system queries the CRUM for a
tag indicating whether a first notice including predetermined CRU
information has already been printed at the machine. If the first
notice has not already been printed, at S210, the machine software
system obtains predetermined data from the CRUM for the first
notice and then S300 is entered.
[0031] At S300, a determination is made whether the machine is
connected to a PC/network or whether the machine is a stand-alone
machine.
[0032] For machines connected to a PC/network, at S310, an
electronic e-mail message is sent to a user(s) indicating the
predetermined information, for example, a message indicating low
CRU life for a particular CRU along with information for ordering a
replacement CRU including identification number and contact
information including vendor(s), manufacturer(s), or third parties
including their respective address, phone number, facsimile number,
e-mail address, Uniform Resource Locator (URL) address, and
combinations thereof. Next, at S320, a first notice is printed at
the machine indicating, for example, a similar message as in S310.
Next, at S330, the CRUM is tagged that a first notice has been
printed at the machine. At, S340, the User Interface (UI) of the
machine may be signaled with a similar message as in S320.
[0033] For stand-alone machines, at S320, a first notice is printed
at the machine indicating, for example, information as in S310.
Next, at S330, the CRUM is tagged that a first notice has been
printed at the machine. At, S340, the User Interface (UI) of the
machine may be signaled with a similar message as in S310 or
S320.
[0034] At S400, a determination is made whether the CRU is at its
end of life using the actual value of the use of the CRU recorded
by the machine, such as the number of copies, prints, cycles, or
other events involving the CRU, compared to a final threshold value
programmed on the CRUM to determine if the CRU use is equal to the
final threshold value for the CRU. For an actual value greater than
or equal to the final threshold value programmed on the CRUM, then
the CRU is at its end of life. If the actual use is less than the
threshold value then the CRU has usable life and the system returns
to the machine ready state. For CRU'(s) at their end of life at
S410, the predetermined data from the CRUM is obtained by the
machine for an end of life notice and then S500 is entered.
[0035] At S500, a determination is made whether the machine is
connected to a PC/network or whether the machine is a stand-alone
machine.
[0036] For machines connected to a PC/network, at S510, an
electronic e-mail message is sent to a user/users indicating the
predetermined information, for example, a message indicating the
CRU has reached end of life for the particular CRU along with
information for ordering a replacement CRU including identification
number and contact information including vendor(s),
manufacturer(s), or third parties including their respective as
address, phone number, facsimile number, e-mail address, URL
address, or combinations thereof. Next, at S520, an end of life
notice is printed at the machine indicating, for example, a similar
message as in S510. Next, at S530, the User Interface (UI) of the
machine may be signaled with a similar message as in S510 and 520.
Next, at S540, the control unit of the machine renders the machine
inoperable until a replacement CRU is obtained and replaced in the
machine.
[0037] For stand-alone machines, at S520, an end of life notice is
printed at the machine indicating, for example, information as in
S510. Next, at S530, the User Input (UI) panel indicator of the
machine may be signaled with a similar message as in S510 and S520.
Next, at S540, the control unit of the machine renders the machine
inoperable until a replacement CRU is obtained and replaced in the
machine.
[0038] S600-S610 and S700-S730 are used where additional notices
are desired for the user. For example, a series of notices may be
programmed into the CRUM or the control unit of the machine to
notify the user at various intervals or thresholds during the life
of the CRU.
[0039] At S600, the actual value of the use of the CRU recorded by
the machine, such as the number of copies, prints, cycles, or other
events involving the CRU, is compared to a second threshold value
programmed on the CRUM to determine if the CRU use is greater than
or equal to the second threshold value for the CRU. For CRU use
that is less than the first threshold value programmed on the CRUM,
the machine will return to the ready state as it would be less then
the final threshold value relating to the end of life of the CRU.
For a value greater than or equal to the second threshold value
programmed on the CRUM, S610 is entered. At S610, the machine
software system obtains specific data from the CRUM for the second
notice and then S700 is entered.
[0040] At S700, a determination is made whether the machine is
connected to a PC/network or whether the machine is a stand-alone
machine.
[0041] For machines connected to a PC/network, at S710, a second
electronic e-mail message is sent to a user/users indicating
predetermined information for example, a message indicating low CRU
life for the particular CRU along with information for ordering a
replacement CRU including identification number and contact
information including certain vendor(s), manufacturer(s), or third
parties including respective address, phone number, facsimile
number, e-mail address, URL address, or combinations thereof. Next,
at S720, a second notice may be printed at the machine indicating,
for example, a similar notice as in S710. Next, at S730, the CRUM
is tagged that a second notice has been printed at the machine. The
User Interface (UI) of the machine may be signaled with a second
notice as in S710 or S720, although an indication of the first
notice may remain at the UI and a second notice may be
unnecessary.
[0042] For stand-alone machines, at S720, a second notice is
printed at the machine indicating, for example, information as in
S710. Next, at S730, the CRUM is tagged that a second notice has
been printed at the machine. The User Interface (UI) of the machine
may be signaled with a second notice as in S710 or S720, although
an indication of the first notice may remain at the UI and a second
notice may be unnecessary.
[0043] In operation, at least one notice including predetermined
information is provided to the user although a series of notices
ranging from two notices to several hundred notices may be made
prior to the end of life notice of the CRU, although less than ten
notices such as two to five notices are envisioned. Various
combinations of CRU information may be programmed as data in the
CRUM for inclusion in the notice(s). The notice may be printed at
intervals by the machine and include an identification code such as
a model number of the CRU and contact information including various
content such as: phone number, facsimile number, street address,
email address, URL address, vendor(s), manufacturer, removal and
replacement instructions, equivalent CRU and respective
identification code, warranty information such as notification that
the CRU is at or is beyond its warranted life, or combinations
thereof. The URL address may be used for ordering, or for obtaining
instructions on obtaining or using a replacement CRU.
[0044] The CRU may be removably securable in the machine and the
machine may automatically print the document after an indication of
a threshold condition. The CRU may include a component containing a
substance used in a marking process and the CRU may be replaceable
in the machine. The CRU may include a consumable substance and/or a
wearable part. The document may be in a human readable medium
and/or a computer readable medium.
[0045] The CRU may include a container having a first volume of a
substance prior to use and a second volume of the substance less
than the first volume after an increase in use. Upon a threshold
occurrence in the CRU, the machine may be disabled other than
printing a document including information about the CRU.
[0046] Various notices based on the data stored in the CRUM
including combinations of information are envisioned. The notice
may include information relating to ordering, returning, using, or
installing the CRU. The notice may include information for a
specific customer. The notice may include information for a
geographic market in which the manufacturer has directed the CRU to
be destined. The notice may include information for a specific
configuration of the CRU. The notice may include information about
the manufacturer. The notice may include information about a future
disablement of the printing system. The notice may include
information in the form of a log of previously printed documents
concerning the CRU. The notice may include information relating to
a return address for recycling of the CRU. The notice may be in the
form of a return label for recycling the CRU. The notice may
include information relating to average print area coverage and
average print rate for the CRU. The notice may include information
relating to a total of the number of prints made using the CRU. The
notice may include information relating to warranty information for
the CRU. The notice may include information relating to
notification of the CRU being used beyond its warranted life. The
notice may include information relating to an estimate of the
remaining life of the CRU. The notice may include information
relating to a percentage of use of at least one of cyan (C) toner,
magenta (M) toner, yellow (Y) toner, and black (K) toner in the
CRU. The notice may include information relating to the date of
manufacture of the CRU. The notice may include information relating
to the place of manufacture of the CRU. The notice may include
information relating to a replacement instruction of the CRU.
[0047] In embodiments of the present invention, various methods and
systems are envisioned. For example, the memory storage device may
include a contact for ordering a replacement CRU and the printing
machine may print a document including at least the identification
code of the CRU and a contact for ordering a replacement CRU upon a
condition in the CRU. The printing machine may send an electronic
mail message including at least one of the identification code of
the CRU and a contact for ordering a replacement CRU to a computer.
The CRU may be a toner cartridge and the memory storage device may
include a contact for ordering a replacement toner cartridge and
the printing machine may print a document including at least the
identification code of the toner cartridge and a contact for
ordering a replacement toner cartridge. The printing machine may
print a document including a URL address for electronic ordering of
a CRU; or a URL address for obtaining instructions on obtaining a
replacement CRU.
[0048] In summary, a system is provided for providing a user with
various printed information about a CRU used in a printing/copying
machine in one convenient location, without the user searching for
information about the CRU. The system is suitable for generally any
printing/copying machine with CRU(s) requiring replacement. The
system provides a simple, low-cost information system for use in an
electronic digital printer, digital copier, facsimile machine, and
combinations thereof. The system is used to better provide
information when it is most needed by a user and to communicate
that information to the user at the printing/copying machine where
the information is most applicable. The information may be stored
on the CRUM. By placing useful data such as an identification code
and contact information on the CRUM, the customer will have access
to the information via a printed document for ordering. Also, data
updates can be made by changing the data on the CRUM as the
cartridge is manufactured. The notice(s) provide useful information
to the user and allow the user to make decisions with respect to
replacing or servicing the CRU. The system can be utilized with
digital xerography and with inkjet. Moreover, the system can be
readily adapted for both black and white and color environments. In
the color environment, the information can be displayed for
individual color inks or toners (C, M, Y, K) as well as combined
into an overall toner/ink usage.
[0049] While this invention has been described in conjunction with
a specific embodiment thereof, it is evident that many
alternatives, modifications, and variations will be apparent to
those skilled in the art. Accordingly, it is intended to embrace
all such alternatives, modifications and variations that fall
within the spirit and broad scope of the appended claims.
