Problem: The Print Quality and Character Pitch keys on the front panel won't work.
Solution: The Operator Panel Function in the printer menu can be used to disable these buttons. If the printer is part of a customized system or if it is used by a number of people, the system manager may have used this option to make sure the printer is always set properly.
Problem: Continuous-form paper is sticking to the paper separator.
Solution: In cold dry weather, static charges can build up and make the paper cling to the paper separator. Try moving the paper guides together so that the paper rests on the guides rather than on the separator.
Problem: Ink smears on paper.
Solution: This may be caused by excessive printhead travel from the centring position when printing narrow columns. Set Centring Position to MODE 1. On ML3391 also try MODE 2. (See Menu Mode).
