❏If you print continuously for an extended period, the paper may temporarily stop feeding 
or the print head may pause for a while. This is to slow down the printing speed and 
prevent the printer mechanism from overheating and being damaged. If this happens, 
you can continue to print, but we recommend stopping and leaving the printer for about 
thirty minutes with the power on. (The printer does not recover with the power off.) After 
you restart, the printer will print at normal speed. 
❏This printer checks the print head on a regular basis to keep the print head clean and 
to ensure you receive premium print quality. If the print head nozzles are clogged, the 
printer automatically cleans the print head. During self-checking, and during 
self-cleaning operation, the print speed may decrease.
❏Make sure Low Speed Mode is not enabled in the printer menu.
&See “Maintenance Menu” on page 105.
❏Uninstall the printer driver, then reinstall it.
&See “Uninstalling the Printer Software” on page 16.
If you try all of the methods above and cannot solve the problem, see the following:
&See “Increasing the Print Speed (for Windows only)” on page 161.
