Defective developing roller (developer 
unit).If the defects occur at regular intervals of 39 mm/1
9/16 (See 
page P.2-4-4), the problem may be the damaged developing 
roller (in the developer unit). Replace developer unit.
If a developer unit which is known to work normally is available 
for check, replace the current developer unit in the printer with 
the normal one. If the symptom disappears, replace the devel-
oper unit with a new one (See page P.1-5-9).
Defective drum (drum unit). If the defects occur at regular intervals of 94 mm/3
11 / 1 6 (See 
page P.2-4-4), the problem may be the damaged drum (in the 
drum unit). Replace drum unit.
If a drum unit which is known to work normally is available for 
check, replace the current drum unit in the printer with the nor-
mal one. If the symptom disappears, replace the drum unit 
with a new one (See page P.1-5-10).

13/16, 82 
mm/3
1/4 or 93 mm/311 / 1 6 (See page P.2-4-4), the problem 
may be the damaged heat roller or press roller (in the fuser 
unit). Replace fuser unit (heat roller or press roller).
If a fuser unit which is known to work normally is available for 
check, replace the current fuser unit in the printer with the nor-
mal one. If the symptom disappears, replace the fuser unit 
(heat roller or press roller) with a new one (See page P.1-5-
14).
Defective paper specifications. Paper with rugged surface or dump tends to cause dropouts. 
Replace paper with the one that satisfies the paper specifica-
tions.
Defective transfer roller installation. The transfer roller must be supported by the bushes at the 
both ends. Clean the bush to remove oil and debris. Replace 
the transfer roller if necessary (See page P.1-5-12).
Defective engine PWB (transfer bias 
output circuit).Replace the engine PWB (See page P.1-5-22).

Defective drum unit. If the defects occur at regular intervals of 94 mm/3
11 / 1 6 (See 
page P.2-4-4), the problem may be the damaged drum (in the 
drum unit). Replace drum unit.
If the defects occur at random intervals, the toner may be leak-
ing from the developer unit or drum unit. Replace developer 
unit or drum unit (See page P.1-5-9 or P.1-5-10).
An additive which was applied to the 
cleaning roller in the drum unit during 
manufacturing was transferred to the 
main charger roller surface of main 
charger unit. (Immediately after the 
printer is installed.)If the defects occur at a regular interval of 39 mm or 1 9/16 
(Seepage P.2-4-4), the problem may be due to the damaged 
main charger roller (in the main charger unit).
Perform the steps 1 to 3 below.
1. Perform the drum surface refreshing for three times (See 
page P.1-3-20).
2. Clean the drum surface (See next page).
3. Clean the main charger roller surface (See next page).
If the problem persists, repeat them more times. If the problem 
still persists, replace the main charger unit (roller).

1-4-11 Cleaning the drum surface
1. Remove the drum unit (See page P.1-5-10).
2. Remove the main charger unit (See page 
P.1-5-11).
3. Hold the drum unit at an angle shown right 
figure.
Use care not to drop foreign objects into the 
drum.
Figure 1-4-6
4. Rotate the drum by rotating the drum gear. 
(in the direction of arrow (A), approximately 
90 degrees)
CAUTION: Do not turn the drum in the 
opposite direction.
5. Lightly wipe the drum surface with a clean-
ing cloth in the direction of arrow (B).
NOTE: Use a cleaning cloth with fine 
seams.
6. Repeat the steps 4 and 5 until the entire sur-
face of the drum surface is cleaned.
NOTE: Do not leave waste textiles of the 
cleaning cloth on the drum surface.

Cleaning the main charger roller surface
1. Lightly wipe the main charger roller surface 
in the direction of arrow (A).
NOTE: Use the cleaning cloth with fine 
seams.
CAUTION: Do not accidentally apply grease 
onto the main charger roller surface.
2. Slightly rotate the main charger roller to a 
new position.
3. Repeat the steps 1 and 2 to clean the entire 
surface of the main charger roller.
NOTE: Do not leave waste textiles of the 
cleaning cloth on the main charger roller 
surface.
4. Lightly wipe the edges of the urethane 
sheet.
CAUTION: Use care not to deform or dam-
age the urethane sheet.

Print example Causes Check procedures/corrective measures
Defective paper specifications. Paper with rugged surface or dump tends to cause unsharp 
printing. Replace paper with the one that satisfies the paper 
specifications.
EcoPrint mode setting. The EcoPrint mode can provides faint, unsharp printing 
because it acts to conserve toner for draft printing purpose. 
For normal printing, turn the EcoPrint mode off by using the 
operation panel. For details refer to the printers operation 
guide.
Defective transfer roller. If the transfer roller is contaminated with toner, clean the trans-
fer roller using a vacuum cleaner or by continuously printing a 
low density page until the symptom has faded away.
Poor contact of engine PWB’s trans-
fer bias output terminal and printer’s 
contact (spring).Check the installation position of the engine PWB.
