• If the deletions are on side 2 of a duplex print or copy, perform the IQ5 Print Damage RAP. Also refer to the White Lines in the Process Direction defect.
• If the deletions are small spots, this can be caused by developer beads on the image. Refer to Developer Beads on the Print or Copy.
• Check the photoreceptor for fingerprints or other marks. If necessary install a new print cartridge, PL 90.17 Item 9.
• If the deletions are small and align with the stripper fingers in the print cartridge, clean the stripper fingers. If necessary install a new print cartridge, PL 90.17 Item 9.
• If the deletions are small and align with the stripper fingers in the fuser module, clean the stripper fingers. If necessary install a new fuser module, PL 10.8 Item 1.
