Operator Panel Menus

Menus make it easy for y ou to change printer settings. Some menus appear only if a specific option is installed in the printer. Other menu items may only be effective for a particular printer language. Y ou can select these values at any time, but they only affect printer function when you use the specified printer language.
An asterisk (*) next to a value indicates the original factory default setting and may vary for different countries. When you select a new setting from the operator panel, the asterisk moves next to the selected setting to identify it as the current user default. These settings are active until new ones are stored or the factory defaults are restored. Changes made from a software application or driver override the user default settings made from the printer operator panel.

Printhead Cable Rubber Backer
Per form the Clean Heads from the diagnost ic mode. Look for a break in the diagonal line of the test pattern. A broke n line indicates one or more print nozzles are not work ing. Run the test again to verify the failure. If there are even breaks in the diagonal line similar to the pattern shown below, replace the engi ne board.
If there is a single break or random breaks in the diagonal line check the following:
• Check the gold-plated contact s, on the end of the cable that connect to the carrier , for dirt and wear. Use only a clean dry cloth to clean the contacts. Also check the cab le for damage. You may need to remove the cable f rom the carrier to inspect it.
• A worn rubber backer results in poor contact between the printhead cable and the print cartridge. Check the rubbe r backer for wear.
• Refer to the test page . Th e tempera ture v alue is Celsius.
Note: Printing slow s to pr event overheating and excess ive ink flow, when the temperature is a bove the normal operating range, or when printing complex graphics. The normal operating temperature range is 60 to 90° F (16 to 32° C). If the printer is operating in a warm environment , >104° F (40° C), excess ive ink may flow from the cartridge. The operating t emperat ure can be found by performing the “Cleaning the Printheads” on page 3-2.

Paper Lifters Operation Theory

As the carrier applies pressure against the clutch lever, located in the gear box assembly, the left and right paper lifters engage, positioning the media into the printer. Media is then pulled through the printer by the combination of torque action between the paper feed motor and the large feed roller, and friction between the paper feed motor and the media.

4. Repa ir Informa t i on

This chapter explains how to make adjustments to the printer and how to remove defective parts.
Note: Read the following before handling electronic part s. When working on the printer, always unplug the printer from the electrical outlet. High voltage is present in the power supply as long as it is plugged into the electrical outlet.

Handling ESD-Sensitive Parts

Many electronic products use parts that are known to be sensitive to electrostatic discharge (ESD). To prevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usual precautions, such as turning off power before removing logic boards:
Keep the ESD-sensitive part in its original shipping container
(a special “ESD bag”) until you are ready to install the part into the printer.
Make the least-possible movements with your body to prevent an increase
of static electricity from clothing fibers, carpets, and furniture.
Put the ESD wrist st r ap on you r w ris t. C on nect the wris t b and to the system
ground point. This discharges any static electricity in your body to the printer.
Hold the ESD-sensitive part by its edge connector shroud (cover); do not
touch its pin s . If y ou are rem oving a pluggable module, use the correct too l .
Do not place the ESD-sensitive part on the printer cover or on a metal
table; if you need to put down the ESD-sensitive part for any reason, first put it into its special bag.
Printer covers and metal tables are electrical grounds. They increase the
risk of damage because they make a discharge path from your body through the ESD-sensitive part. (Large metal objects can be discharge paths without being grounded.)
Prevent ESD-sensitive parts from being accidentally touched by other
personnel. Install printer covers when you are not working on the printer, and do not put unprotected ESD-sensitive parts on a table.
If possible, keep all ESD-sensitive parts in a grounded metal cabinet
(case).
Be careful in working with ESD-sensitive parts when cold weather heating
is used because low humidity increases static electricity.

The user is directed, in the Printer Control program, to perform the head to head and bidirectional alignment adjustments after replacing a print cartridge.

Removal Procedures

The following procedures are arranged according to the name of the printer part discussed. Unplug the power cord before removing any parts.

Releasing Plastic Latches

Many of the parts are held in place with plastic latches. The latches break easily; release them carefully . To remove such parts, press the hook end of the latch away from the part to which it is latched.
