Banding due to ink cartridge replacement while printing Troubleshooting Someone has removed an 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 an Ink Cartridge while the printer is printing. Only replace/remove Ink Cartridges 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 removing the Ink Cartridge). 34-inch Rice Paper not supported The roll width is 34 inches (non-standard), and the pinch wheels can't control the edge of the paper, causing ink smears and printhead crashes. Worm marks on HP Coated Paper with light area fills Light bands (S-shaped) in the direction of the media axis when light area fills are printed, causing an unacceptable print-quality defect.
● Print the Service Configuration Print and check whether the ambient humidity is very low (below 30%). Increasing humidity may help to reduce the severity of the problem. NOTE: The paper is causing the problem and not the printer. Do not attempt to replace printer parts to solve this problem. Solving paper-handling problems The front panel keeps indicating that paper Is misaligned or incorrectly positioned. ● The roll may be loaded the wrong way. The paper should load over the roll toward you. ● Check that the paper is correctly loaded onto the spindle. ● The paper may be loaded at an angle. The right-hand edge must be aligned with the blue line on the Print Platen. NOTE:
Ensure that the paper is wrapped tightly on the roll. This is a very important step to remember because if this is not done, the paper may be loaded at an angle, causing the paper to be rejected. ● The Line Sensor may be malfunctioning.
