SECTION 2 – Troubleshooting
The following troubleshooting guides are provided to assist you in solving any problems that might occur
with the Digital Color Printer. We have tried to make them as complete as possible. The best advice we can
offer is to make sure that the system is set up properly, plugged in, and that it has an adequate supply of ink
before attempting to troubleshoot any problem.
WARNING
DO NOT REMOVE THE SIDE COVERS OF THE PRINTER!
THERE ARE HIGH VOLTAGES PRESENT BEHIND THE COVERS!
Print Quality Issues:
Many things can contribute to print quality issues. Here is a list of things to check:
•
To reduce print quality issues, the print engine should remain powered-on. Even in its standby state,
the printer will run routine maintenance cycles to help keep the printhead nozzles hydrated and clean.
•
Verify that the media you are printing on is an “inkjet suitable” media. See Paper Types below.
•
Verify that the “graphic” you are printing is of a high quality. See Graphic Types below.
•
Check to be sure the printer has an adequate supply of ink (30% or more) in all five Ink Tanks.
•
Check to be sure all five color tubes, at both sides of the printhead cartridge, have ink filling them.
If not, check for a pinched color tube (finger on Forwarding Roller Guide Assembly may be pinching
tube), check related Ink Tank, and or the system may need to be re-primed. Please refer to the
Troubleshooting section for information on correcting these issues.
•
Try removing air bubbles from printhead and system using the Toolbox utility feature “Circulate Ink”;
while lightly tapping on the ink tubes and printhead cartridge.
Note : Do not run the Circulate Ink feature more than twice in a row.
•
Try removing or inserting the “Head Media Guide”.
•
Try “Cleaning the Lip of the Printhead Cap”.
•
Try “Cleaning/Replacing Service Station Items”.
•
If you are still experiencing print quality issues; try “Replacing the Printhead Cartridge”.
