Primera Technology LX900 Benutzerhandbuch

During this process the printer will make several loud

whirring noises.  This is normal! This is the sound of a pump

forcing ink through the nozzles.  If you do not hear this sound,

the clean purge print did not complete successfully. Try again.
3B. Deep clean the cartridge.
(Optional - Only clean in this manner if no back up printheads

are available and if the above cleaning procedure have yielded

little improvement.) Remove the printhead from the printer,

remove the cartridges from the printhead. Run warm/hot

water through the printhead wells. At the same time use a wet

paper towel and repeatedly press on the print nozzle to wick

the ink out. Do this until almost no ink is running out of the

nozzles. Thoroughly and completely dry the printhead.

Especially, make sure no water remains near the copper contact

areas. Finally, clean the print carrier copper contacts on the

printer itself with isopropyl alcohol on a paper towel.
3C. Preventing clogged nozzles.
Clogged nozzles on the printhead can be caused by non use of

the printer for extended periods of time. Follow these guide-

lines:
•

Always keep the LX900 plugged in and turned on. The

printer will do periodic maintenance to make sure the noz-

zles do not clog. 

•

Never store a used printhead outside of the printer. The

nozzles will dry out with exposure to air. If you must store

a printhead outside of the printer, place full or empty car-

tridges in the printhead and put the entire printhead and

cartridges in a sealed plastic bag. 

•

Use the printer regularly!

Change your quality setting. The lowest

(and fastest printing) quality may not be sufficient for

many photos or graphics. The highest quality setting may

cause ink to bleed on certain graphics in combination with

certain label stock. Increasing the quality increases print

time because the printer makes more passes over the

media.

Printhead/Cartridge. The cartridge may be empty

or defective. The printhead nozzle for one color could be

clogged. The fastest way to diagnose a quality problem is

to have backup printheads and cartridges available for

comparison testing. If one color is missing, replace that

color cartridge(s). Next try replacing the print head.
