correspond to the same conditions that the calibration was done in. To solve the problem, perform the
Accuracy Calibration in the new environmental conditions (see Using your printer).
Printhead crashes/smears on high-density prints
using coated paper
High density prints can cause cockle mainly on HP Coated Paper. This causes two main problems:
1. Cockling in the borders - Because the printer places too much ink on the Coated Paper, the
borders of the print become raised, causing the Printhead to crash against the paper. To solve the
problem, try the following.
●
Change the paper margins to 15mm, either in the Front Panel or in the Driver. If the customer
is printing PostScript images, send them a PPD file containing the extended margins of
15mm.
2. Cockling within the print - If the printer places too much ink within the print, the paper starts to
ripple, causing the Printhead to smear against the paper. To solve the problem, try the following.
●
Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
●
Never use HP Coated Paper for High Density prints. As a substitute use HP Heavy Coated
Paper.
Banding due to ink cartridge replacement while
printing
A user has removed the Ink Cartridge while the printer was printing, which has caused the printer to
stop. If the user does not replace the Ink Cartridge immediately, when the printer starts to print again, a
band will appear in the position where the printing restarted. This is because the wet ink interacts with
the dried ink on the paper causing the band to appear. To solve the problem, try the following.
●
Do NOT remove the Ink Cartridge while the printer is Printing. Only replace/remove Ink
Cartridges in between Prints.
●
If the Ink Cartridge was replaced due to the “Empty” status on the Front Panel, then advise the
customer to replace the Ink Cartridge when the “Very Low” status is showing on the Front Panel.
●
Reprint the file (without remove the Ink Cartridge).
34" Rice Paper not supported
Roll width is 34" (non-standard), and the pinch wheels can't control the edge of the paper, causing ink
smears and printhead crashes.
