Troubleshooting Of The Control Panel - Ricoh HL-F1 Field Service Manual

• Is it possible to print after reducing the data of a document?
Yes: Replace the main PCB.
P-4 Headers or footers are not printed out even though they are viewed on PC screen.
User Check
Most laser printers have a restricted area that cannot be printed on. Usually the first two lines and last two
lines of text cannot print (leaving 62 printable lines). Adjust the top and bottom margins in your document
to allow for this.
P-5 The printer sometimes prints a couple of characters and then ejects the page.
User Check (For DOS environment only)
The application printer emulation setting and the printer's emulation do not match. Check in the application
software which printer you have selected to make sure the printer is set up correctly.
Remember that the printer emulates widely used printer selections:
HP Laser Jet 6P, HP Laser Jet 6P, Epson FX-850, IBM Proprinter XL
Try setting the printer into HP emulation and then select the HP LaserJet 6P printer in the application software.
