Hello,

First part to replace would be ITB

Also update the printer FW to 3.8 found at the link below. Also check the Toner Collection Unit on the left side of the machine and make sure its not empty.

One solution is to identify if it is a repetitive defect (does the print quality defect appear multiple times on the printed page?). If this is the case, use a ruler to measure occurrences of repetitive image defects to help solve image-quality problems.

Place the ruler next to the first occurrence of the defect on the page. Find the distance between identical defects and use the table below to identify the component that is causing the defect.

Primary charging roller1

27 mm (1.06 in)

Developer roller11

32 mm (1.26 in)

Registration roller

42 mm (1.65 in)

Secondary transfer roller

50 mm (1.97 in)

Fuser film2

58 mm (2.28 in)

Pressure roller2

69 mm (2.83 in)

Photosensitive drum1

75 mm (2.95 in)

　

1The primary charging roller, photosensitive drum and developer roller cannot be cleaned. If any of these rollers are indicated, replace the toner cartridge.

　

2The primary fuser sleeve unit or pressure roller cannot be cleaned because they are internal assemblies in the fuser. If one of these assemblies is causing the defect, replace the fuser.
