### Improve the Print Quality

If you have a print quality problem, print a test page first. If the printout looks good, the problem is probably not the machine. Check the interface cable connections and try printing a different document. If the printout or test page printed from the machine has a quality problem, check the examples of poor print quality in the table and follow the recommendations.

IMPORTANT
  Using non-Fuji Xerox supplies may affect the print quality, hardware performance, and machine reliability.

1. To get the best print quality, we suggest using recommended print media. Make sure you use paper that meets our specifications.
2. Check that the toner cartridge and drum unit are installed correctly.

(DocuPrint P228 db/DocuPrint P268 d/DocuPrint P268 dw) If the problem only occurs during 2-sided printing, check for torn paper in the 2-sided tray, verify the 2-sided tray is inserted completely and the back cover is closed completely.
Curled or wavy | Check the paper type and quality. High temperatures and high humidity will cause paper to curl. If you do not use the machine often, the paper may have been in the paper tray too long. Turn over the stack of paper in the paper tray. Also, fan the paper stack, and then rotate the paper 180° in the paper tray. Open the back cover (face-up output tray) to let the printed paper exit onto the face-up output tray. Choose Reduce Paper Curl mode in the printer driver when you do not use our recommended print media.

After you have finished printing, reset the levers back to their original positions. Pull up the levers until they stop. Make sure envelopes are printed with the back cover (face-up output tray) opened. Make sure envelopes are fed only from the manual feed slot.
