I have a BJC-4200 printer on a Pentium II system running Windows 98.
Prior to the first page of a print job printing, a single page comes out, with only a few characters in the top left corner. The characters are: [CKHD; except the C and the K are overlapped.
This happens when printing from different programs, and whenever the printer has been turned off. ie. the first printed page after it has switched on comes out as described.
Before this it had been working fine for 18 months.
I have tried reinstalling the driver, and different versions of it, with no luck, and the separater page is also disabled.
