4.2 Cache problem
(The carriage pause too long at the two ends of the lead rail during
the printing process.)

There might be two aspects that cause this problem, below are the causes explanations
and solutions.

Excessive image size or excessive file gross result in long data processing, and thus
relate to printing data transmitting slowdown. Normally when processing some large
image or a great amount of images, adopt the mode of print after RIP.

A virus might have affected the computer. Execute anti-virus operation periodically.
4.3 Printing error
(with a message reads “Device is busy, please check the media
location plate, raster reader and motor driver, try again.”), The causes might be:

Anti-crashing attachment enabled

Media positioning attachment enabled

Encoder malfunction due to accidental crash with obstacle.

Data transmitting error due to abrasion of the optical fiber.
4.4 Automatic head height adjustment malfunctions

When a problem with the head height adjustment assembly occurs, check and see
whether there is non-working or retards.

If the carriage can only be operated going up but not going down. Check if there are too
many dirts makes the electromagnet clog and not able to effect action, or if the head
height finder is broken.
4.5 Printing quality troubleshooting
Abnormality Troubleshooting
Horizontal banding

Check horizontal alignment

Check color calibration
Unclear(blurred) printing

Check if the head height is right for the printing job, normally
2mm would be optimum.

Clean the nozzles surface
