Ink Suction Amount In The Cleaning Mode - Canon SmartBase MPC400 Service Manual

3.5 Ink Suction Amount in the Cleaning Mode

The printer has five cleaning modes (A to G). Cleaning is executed for maximum effectiveness and
efficiency. The cleaning operation is selected depending on the respective condition. The ink suction
operation differs depending on the condition at three occasions: Operation by the user, cover open/
closing, and before printing starts.
• Operation by the user: Manual ink suction (Including printer driver operation)
• Cover open/closing: Cleaning at printer arrival
• Before printing starts: Other than manual suction

*1 If the preconditions overlap, the stronger suction will take priority.
Cleaning A < Cleaning D < Cleaning E < Cleaning F < Cleaning G
*2 In the case of the boxed preconditions, the suction starts right after the precondition is executed. For
other preconditions, suction is executed right before the printing starts or during printing.
*3 Ink tank replacement is detected when the ink tank's status changes from H to L.
*4 Printing of EEPROM contents, etc., with the printer alone.
*5 Purging operations will be performed after 24 hours only the first 5 times, after which purging will
occur at 60 to 336 hours intervals.
When checking the functions of the purge unit, measure the suction amount for a manual
suction.
