Maintenance Drop-Down
Perform maintenance tasks on the Printer/Printhead.
The printer automatically performs maintenance tasks to keep the printhead and
ink system performing properly. The following features can be used, as needed, to
provide supplemental maintenance.
CAUTION : Over-use of these features can negatively affect print quality and
printer performance.
Circulate Ink –Pumps ink through the ink system and Printhead.
Use to help fill ink lines and purge air from the system.
Full Clean Printhead – Runs a routine, similar to Printhead Priming, to
thoroughly flush and clean the Printhead. Use to clear air from the system, clear
inkjet nozzles, hydrate the wiper roller and improve print quality. In general, this
feature should NOT be used more than once a day. If used too often, wiper roller
oversaturation may occur which can cause print quality issues.
Normal Clean Printhead – Circulates ink, purges nozzles, wipes/cleans the
surface of the Printhead. Use to help clear inkjet nozzles and improve print
quality.
Quick Clean Printhead (Wipe Printhead) – Wipes/cleans excess ink from Printhead Surface. No ink is
electronically ejected in this process, but ink is still wicked from the head during this process.
Inspect Sled – Moves Service Station to an accessible position, out from under the Printhead, to allow for
inspection, cleaning or service. Printhead is also presented in Printhead Opening for inspection and manual
cleaning using a lint free cloth dampened with DI water.
End Inspection – Gives printer back control over Service Station; so printer can perform Printhead maintenance
and capping.
Wiper Transfer – In this process the wiper roller is rotated to transfers any debris and excess ink from the Wiper
Roller to the Squeegee Roller within the Service Station. This process is also used to maintain proper Wiper Roller
moisture content. If Wiper Roller gets too dry; it cannot remove the ink and debris from the Printhead surface. If
Wipe Roller gets too wet; it may leave debris and ink behind, when attempting to clean the Printhead surface.
Service Drop-Down
The following features can be found under the Service drop-down list.
System Deprime – Pumps ink from Printhead and ink system, back into Ink
Tanks. Use this feature before replacing the Printhead Cartridge or transporting
the Printer.
Shutdown – Powers-down the Print Engine and Touchscreen.
Same as using Soft-Power Button.
When this feature is selected, the printer will perform head maintenance and then
cap the Printhead before powering-down the Print Engine.
NOTE : For best system performance, it is recommended to keep Print Engine
powered-up ( Soft-Power light illuminated ) at all times.
Restart – Shuts-down and restarts the Print Engine and Touchscreen without
perform long-term shut-down maintenance routines. Printer will still go through normal startup process at power-
up. This feature is useful when a printer re-boot is needed. It takes less time than using the Shutdown feature.
Restart UI – Shuts-down and restarts the Printer’s Touchscreen Display without perform any Print Engine
maintenance or Print Engine startup routines. This feature is useful if the Touchscreen becomes unresponsive.
