Ink Cartridges
Each ink cartridge contains 30 grams of liquid ink, and is rated for as
much as 700 pages of text.

Also, the ink cartridge has an electronic label which is sensed by the
cartridge sensor. The ink is nontoxic, but contains isopropyl alcohol
and should not be swallowed or gotten in the eyes. It will permanently stain clothing.
To prevent ink leaks, always ship the printer with the ink cartridges
installed, and with the carriage locked in place.
Also make sure the four printheads are capped before switching the
printer off. A star (*) is displayed when the heads are automatically
capped.

•
Magnifier
Refer to the parts catalog for part numbers of special tools. When
taking voltage readings, always use frame ground unless another
ground is specified.
When you use the syringe, clip the end of the tip so it will fit over the
small tube connectors and into the ink joints.
NOTE: Be careful not to separate the syringe plunger from the body
of the syringe. The ink may leak and stain clothing and other items.
Make sure the machine is in a suitable service area and place a drop
cloth under the machine when you service it.
Printer Emulation
Before you use your printer with most software programs, you must
select the appropriate printer driver from that program’s printer
selection menu. When you select a printer from the list, a driver is
installed that allows your documents to be printed correctly on your
printer.
If the printer does not appear on the list in your program, you can
use any of the following printer driver emulations, listed here in the
order of their priority . Choose the first printer on the list that appears
in your program’s list of printers.

If none of these choices appear in your software, you may choose
another PostScript printer. However, if you choose a non-color
printer, your output will have only black print.

Buttons
Five buttons on the operator panel control the printer. There are two
operations for each button, depending on the state of the printer and
whether Alt is pressed.
1. Menu and Menu -
Press Menu to display the menu system, whether the printer is
Ready or Not-Ready. If a job is active, the Ready indicator is turned
off, and the menu is displayed after the current job has completed
printing. If the menu is already active, pressing Menu displays the
next menu item on the top line of the display.
Menu - is accessed by pressing Alt + Menu, and mov es to the pre vious menu item.
2. List+ and List -
When the menu is active, these buttons display the list of items on
the second line of the display. Press Alt + List+ (List - to move to
the previous list item.
3. Select And Return
Select only operates when the menu is active.
If the top line of the menu is active, pressing Select causes the lower
line to become active. If the lower line of the menu is activ e , pressing
Select selects the current value being display ed. If the current v alue
is a function, such as printing a test, it is executed. If the current
value is a setting, such as High Speed, it becomes the permanent
default.
Return is activated by pressing Alt + Select and it only operates
when the menu is active. If the lower line of the display is active,
pressing Alt causes the upper line of the displa y to become activ e . If
the upper line of the display is active, pressing Alt exits the menu
system in the Not-Ready state.
4. Start/Stop and Reset
If the Ready light is on, pressing Start/Stop turns off the Ready light
and the printer stops processing information. The current job will be
interrupted.

Printhead Capping
The printheads are capped automatically after they have been in the
home position for a few seconds. When the printheads are capped,
a star (*) appears in the display. Do not turn the printer off without
the heads being capped. If the heads are left uncapped, the ink dries
out and print quality is affected.
Adjusting The Printhead Position Lever
The printhead position lever is the green lever attached to the carriage.
For optimum print quality, make sure this lever is adjusted according
to the density of the ink in the document and the thickness of the
paper being used. Setting the lever at position 1 sets the distance
between the printhead and the paper at the minimum distance.
Follow these recommendations:
Position 1

If the head is positioned too close to thick paper, envelopes, or
densely inked graphics, the ink could be smeared. In general, keep
the head position as close as possible to the paper.
Also, be sure that quality coated paper is being used for best print
quality.

2. Diagnostic Information
Start
When the covers are remov ed, y ou will get a Cov er Open error code.
To prevent this, tape the cover open interlock arm in the closed position on the operator panel.
All voltages in the service checks are positive unless otherwise
noted. When measuring voltages, always use frame ground unless
otherwise specified.
Visually check the machine for obvious problems such as ink leakage, and worn or missing parts. Also reseat all cables, and check for
good connections.
Note the error code number, if one is displa yed in the oper ator panel,
and the number of beeps sounded. If you have an error code, go to
the “Error Code Table” on page 2-2 and follow the instructions for
that error code.
If no error code is present, check the NVRAM for the Last Error
code. (See the procedure in “Controller Diagnostics” on page 3-9).
If no error code number is displayed, or you cannot access Controller Diagnostics to check the last error code, or you have no clear
symptom, continue with this Start procedure.
If you proceed through Start, the Error Code T ab le, and the Operator
Codes and Symptom Table without determining an error code or
symptom, go to “Undetermined Problem Service Check” on page
2-47 and then return here to Start.
When a service check instructs you to end the call, you should run
“Test Print A” on page 3-3.
Check the following:
1. Turn the printer off. Make sure the carriage lock is disengaged,
then turn the printer on. If there is no indication of power in the
printer, go to the “Power Supply Service Check” on page 2-39.
Diagnostic Information 2-1
4079-00X
2. If the printer has power but does not complete POST, with
Ready on the display, go to the “Operator Panel Service Check”
on page 2-31.
3. Run Test Print A. To enter Controller Diagnostics, press and
hold Menu and Print Buffer while turning on the printer. After the
POST is complete, the first item in the Controller Diagnostics
menu is displayed. Use coated paper if a vailable. If you use regular paper, allow f or some color conv ergence. If an error code or
detectable symptom occurs, go to the “Error Code Table”. If you
have a symptom only, go to the “Operator Codes And Symptom
Table” on page 2-8.
4. Turn the printer off and connect it to a host computer. Turn the
printer on and send data from the computer to the printer. You
can use the test print for this. If the data does not print as it was
sent, go to the “Host Print Service Check” on page 2-22.
Error Code Table
To use this error code table:
1. Turn off the printer, wait four or more seconds, then turn on the
printer.
2. Note any error code number that appears in the display, look for
that code in the tables below, and take the indicated action.
•
If two error codes are listed in the table: the top number is displayed if the controller board is installed; the bottom number is
displayed if the controller board is removed.
•
Some error codes are operator-correctable. See “Operator
Codes And Symptom Table” on page 2-8.
•
Other codes indicate the printer is performing an operation; no
action is needed. For example, “04 Reset”, or “05 Self Test”
means the printer is running POST.
3. If no error code is displayed, count the number of beeps and
look for that number in the tables.
4. If no error code is displayed, and no beeps are heard, look for
the symptom in the table and take the indicated action.
5. If you are unable to correct the problem using this index, go to
the “Undetermined Problem Service Check” on page 2-47.
Note: If POST fails and a message is displayed, disregard the message and count the number of beeps.
