Print quality troubleshooting

 If printing over a LAN, it is possible that the LAN is too slow to meet the

requirements of the print job.

If this is the case, the following corrective measures can be taken:

1 Do not use the computer while printing. Close applications that use a large

amount of

computer resources.

2 Convert the file PDF. Formats like PDF require less resources to print, which

may s

olve your banding problem.

Lines are Missing, Too Thin, or Too Thick

Description of problem

Shown below is an example of what you might se

e if you have this problem:

Corrective Action

1 Check that the paper type loaded corresponds to the paper type selected in

the f

ront panel and in the software. You can verify the paper type selected

through the Front Panel (Main Menu/Paper menu/View loaded paper).

2 C

heck that the appropriate print quality settings are being used (refer to the

er’s Guide for more information). Select the custom print quality options in

the Print dialog, and if you are using best quality and glossy paper, try

turning on the Maximum detail option. Reprint the job in case the problem

has been solved.

3 If the r

esolution of the image is greater than the printing resolution, a loss of

line qu

ality may be seen. You can find the Max. Application Resolution

option in the Windows driver dialog's Advanced tab, under Document

Options > Printer Features. Reprint the job in case the problem has been

solved.

4 C

heck the Printhead alignment status. If the status is PENDING, perform the

Pri

nthead Alignment (Main Menu/Image Quality Maintenance/Align

Printheads). After alignment reprint the job.

5 C

heck the paper advance calibration status. If the status is PENDING,

perf

orm the paper advance calibration (Main Menu/Image Quality

Maintenance/Paper Advance Calibration/Calibrate Paper Advance). After

calibration reprint the job.

6 U

se Part 3 of the Image Quality Diagnostic Print, check if there are a

sig

nificant amount of nozzles out in the color that is actually causing the

problem (if see you a problem with the Black color in the customer print, then

only check the Black printhead in the Image Quality Diagnostic Print). If

there is a significant amount of nozzles out then replace the defective

Printhead.
