service preventative maintenance kit
during the life of your printer, components that are used constantly can wear out with time and use.
to avoid these components being so worn that the printer breaks down, the printer keeps track of the number of cycles the printer carriage makes across the axis of the printer. the number of cycles can be seen by going to printer setup/utilities/statistics.
the printer uses this number to advise you of the need for preventive maintenance, and displays the message shown below:
this message means that the components are nearing their end-of-life. you can continue printing for quite some time, depending on your use of the printer. however it is strongly recommended that you call your hp representative and arrange for a preventative maintenance on-site visit.
the service engineer can then replace the worn parts, this will ensure the life of the printer for a further period.
the benefits of arranging a service engineer visit when the front-panel displays this message are two fold:
1. the printer components can be replaced at a time which is convenient for you and so will not disturb your daily work flow.
2. when the service engineer performs a preventative maintenance visit he will replace several parts at once. this will prevent the necessity of repeat visits and more printer "down time".
user maintenance kit
the printer uses liquid ink and this can form a mist inside the printer, the mist settles on the printer components and after a while, depending of the amount of use the printer has, ink deposits form inside the printer. to avoid potential problems you can order a kit with all the parts that you need to clean the printer with. the kit contains:
· lens covers kit
· carriage interconnect wiper kit
· carriage rods lubrication kit
· roller lubrication kit
· platen cleaning instructions
use the contents of this kit to perform the following maintenance procedures and the frequency shown:
cleaning the platen
marks underneath the media or at the media edges can be caused by accumulated ink deposits on the platen transferring to the media. the ink deposits can be seen mostly in the areas where the edge of your media rests on the platen. the printer routinely removes these ink deposits every time you load roll media. however, depending on your printer usage, this is sometimes not sufficient. there are two procedures for cleaning the platen, automatic and manual.
see the user maintenance kit for the frequency for this procedure.
click on
this icon to run an animation sequence of the manual cleaning procedure.a printable version of the sequence is also available so that you can take the key illustrations to the printer, if it is remote from your computer.
automatic platen cleaning
this setting enables you to remove the ink deposits from the platen using the media you have loaded. the printer moves a portion of the media backwards and forwards over the platen.
every time you load media
to trigger the automatic cleaning process to be performed every time you load media, set:
utilities/clean platen/automatic clean=on.
on demand
to manual trigger the automatic cleaning process to be performed on demand, set:
utilities/clean platen/clean now?-/automatic.
manual platen cleaning
detailed here is the process for the manual platen cleaning.
ensure that you have unloaded the media before performing these procedures.
1. open the window.
2. with a dry brush, remove the ink deposits from the cutter groove.
3. also with the dry brush remove the ink deposits from the platen surface.
4 use a clean slightly damp absorbent lint-free cloth to wipe off the loosened ink deposits from the platen. however, do not wipe the platen wheels with this cloth.
do not use commercial cleaners or abrasive cleaners. do not wet the platen directly because you will leave too much moisture behind.
use isoproply alcohol to dampen the cloth.
5. clean the cutter ramp as shown below with the damp cloth.
6. clean the exposed part of the wheels as shown below with a slightly-damp absorbent lint-free cloth. it is important that the cloth is not too dirty, otherwise you will leave too much moisture behind and the wheels will not work well.
to turn the platen wheels so that you can clean the whole circumference, perform the following:
7. close the window of the printer.
8. select the printer setup menu in the front-panel.
9. select "utilities" in the printer setup menu and press the enter key.
10. select "clean platen" in the utilities menu and press the enter key.
11. select "clean now ?-" in the utilities menu and press the enter key.
12. select the "manual" option and press the enter key.
13. open the printer window.
14. use the ↓ & ↑ keys to move the wheels through a fifth of a turn.
do not touch the rotating wheels directly with your hands.
15. clean the exposed part of the wheels.
16. repeat steps 14 and 15 three more times to clean the whole circumference of the wheels.
17. close window to exit.
carriage interconnect wiper
when you replace the printhead, check the empty slots to see if they need cleaning. in some extreme cases it is possible that the printer will not recognize a printhead when it has been installed. this is due to the build-up of ink deposits on the electrical connections between the printhead and the printhead carriage.
included with your hp designjet printer, is a carriage interconnect wiper. this must be used for cleaning the electrical interconnects of both the printhead carriage and the printhead.
for the frequency that this procedure should be performed see user maintenance kit.
if the front-panel persistently displays the message "reseat" next to the printhead try performing the procedure shown here.
to see how, click here . a printable version of the sequence is also available.
do not touch, wipe or attempt to clean the printhead nozzles. this can damage the printhead and reduce print quality.
after waiting a few moments to allow both connectors to dry, replace the printhead into the carriage assembly printhead installation.
lens maintenance
the optical sensor on the printhead carriage has a lens cover to protect if from ink mist and other contaminants.
the lens cover is located on the lower right side of the carriage.
over time, this lens cover will get dirty and need to be replaced. when the printer detects that the lens cover is dirty, it will display the message:
you should replace the lens cover to prevent any problems with printer operations due to the optical sensor.
replacement lens covers are provided with your printer and are stored inside the window of the printer. you may replace the lens cover immediately when you see the message or wait until the next time you need to replace a printhead.
you can continue to print if lens maintenance is displayed, but after awhile the printer will not be able to continue and the front-panel will display a "system error".
replacing the lens cover
1. press the top key and press enter. go to utilities/lens maintenance.
2. the printer will display the message:
do not open the window before the above message is displayed.
3. you will find a small slotted white plastic insert on the left end of the media roller. with a soft tissue carefully clean the top of the plastic insert.
4. remove the dirty lens cover from the printhead carriage by pulling it straight out of the slot on the right side of the printhead carriage.
5. take a new lens cover from inside the window of the printer, lens covers are also available from the user maintenance kit.
6. making sure that you do not touch the glass portion of the lens cover, install the new lens cover into the slot. make sure the lens cover is firmly in place.
7. close the printer window and press the enter key.
if the "lens maintenance advised" message is displayed after you have replaced the lens cover with a new one, contact your hp representative.
