The I-Prime signal is sent over the parallel interface (pin 31) and will automatically override any settings you have made using the front panel buttons. To eliminate this problem, enter the program MENU (hold SHIFT button while pressing SEL/MENU button) and change the I-Prime item (in the Parallel I/F group) to Invalid.

…the Print Quality and Character Pitch buttons on the front panel won’t work?

The Operator Panel Function item on 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.

…static electricity causes the paper to stick?

In cold, dry weather, static charges can build up on continuous-form paper. This can make the paper cling to the paper separator. If you have this problem during high- volume printing jobs, try moving the single sheet paper guides on the separator to- gether so that the paper rests on the guides rather than on the separator itself.
