SECTION 4
MAINTENANCE
Purging the Nozzles
If the inkjet cartridge sits inactive for a period of time, ink may dry in the nozzles. Printing may not
remove these “ink plugs” from the nozzles. White streaks will then show up in the printed text or graphic.
In order to obtain better print quality, these ink plugs need to be forced out or purged. A Purge routine is
built into the printer. It can be accessed from the LCD panel on the Printer from the MENU key. If this
does not solve the problem then proceed as follows:
1. Wipe the printhead with a damp cloth as described in Section 4 " Cleaning the Inkjet Cartridge ".
2. Perform the Purge routine from the Printer by pressing the MENU key momentarily and then the +
key. Load media and press the ENTER key to purge. Repeat if necessary.
3. If the problem persists, replace the ink cartridge.
NOTE: For more information, refer to “
Troubleshooting HP Ink Cartridges ” in Section 5.
Jams in the Printer
If a jam occurs; STOP the Printer. Up to 10 missed addresses can be recovered at the printer control panel.
(See Section 3 – Operating the Printer “
Print Recovery After a Jam ”.
Some possible reasons for jamming are:
1. Feeding more than one piece of media (overlapping, double-feeding). Reset separation.
2. Damaged media, such a dog-eared (turn down corners).
3. Media that is not stiff enough may not be usable. Media that meets Postal stiffness requirements
for automated feeding is acceptable for use in the printer.
4. Envelopes that are caught under the flap of another envelope (nested) or stuck to one another may
cause jamming.
Removing Jammed Media
1. It may be necessary to move one or more of the printheads to gain access to the jammed media.
Take care in removing jammed media to prevent damage to the print heads. All pieces of the
jammed media must be removed from the feed path.
2. Follow the instructions in Section 3 – Operating the Printer “ Print Recovery After a Jam ”.
Cleaning the Printer
WARNING
THE PRINTER IS A PRECISION MACHINE THAT SHOULD BE CLEANED
REGULARLY TO INSURE MANY YEARS OF SERVICE. BEFORE PERFORMING
ANY MAINTENANCE DISCONNECT THE MACHINE FROM ITS POWER SOURCE!
The Printer must be cleaned regularly of accumulated paper dust and ink. Depending on the types of media
that are run, paper dust may accumulate within the printer and on the transport. To properly clean the
printer, unplug it from the power receptacle and remove the covers.
The internal areas are best cleaned with a vacuum that has a soft brush attachment to help loosen the dust
particles. Take care not to damage the PC Boards or electrical wiring.
The exterior of the machine may be cleaned with any standard household cleaner which is non-abrasive and
does not contain plastic harming solvents.
