Ink system tips For best results, always follow these guidelines: ● Follow the instructions on the front panel during installation. ● Allow the printer and the printhead cleaning cartridge to clean the printheads automatically. ● Avoid unnecessary removal of the ink cartridges and printheads. ● The ink cartridges should never be removed while the printer is printing. They should be removed only when the printer is ready for you to replace them. The front panel guides you through the replacement procedure. ● Make sure that you comply with all applicable laws and regulations when disposing of ink system consumables. NOTE: Shake the ink cartridges and printheads vigorously before installing them. Align the printheads The printer performs printhead alignment whenever printheads are replaced. If no substrate is loaded when a printhead is replaced, the printer will perform the alignment the next time you load substrate. You may also be recommended to align the printheads to solve a print-quality problem. Automatic alignment First make sure that you have a roll of opaque, white substrate loaded in the printer. Colored substrates, glossy canvas, and transparent materials such as translucent bond, clear film, tracing substrate, and vellum are not suitable for automatic printhead alignment; for these substrates, you should align the printheads manually (see Manual alignment on page 10). To request printhead alignment from the front panel (if the alignment is not performed automatically), select the icon, then select Image quality maintenance > Align printheads > Auto PH alignment. To request printhead alignment from the Embedded Web Server, select the Setup tab, then select Printhead alignment > Automatic printhead alignment > Print. ENWW Ink system tips 9
