When Not Using The Printer For More Than 2 Weeks - Oki IP-6620 User Manual

When not using the printer for
more than 2 weeks
Always set the printer power to on to perform the fill cap operation.
What is fill cap?
š This function fills the caps with ink to soak the print heads (nozzle surface) in order to prevent clogged nozzles
due to ink drying.
Use this function also when several cleaning operations could not clear the clogged nozzles.
The printer automatically performs the fill cap operation, which keeps the print heads in good condition, when 72
hours has elapsed after it entered the standby state (then once every 3 days).
It is therefore recommended to always keep the printer turned on.
If the printer stays turned on and is not used for 2 weeks or longer, you will have to perform the wash operation, fill
the ink system, and execute daily maintenance following the procedure below.
If you have to leave the printer turned off for a long time, follow the instructions below to perform service cleaning
before turning the printer off.
