Adjustment after Replacing the Laser Unit
Close the front cover and attach the left cover.
- Attach the left cover before turning on the main power switch. Laser beams can seriously damage your eyes.
Plug in and turn on the main power switch.
Download the data of the new laser unit to the main body with SP2-110-005. 4. Check that SP2-119-001 to 003 is "0."
- If it is not "0", perform SP2-110-005 again.
- If it is not executed correctly, outputs will be abnormal (magnification and color registration errors), and SC 285 may occur.
Turn off the main power switch and disconnect the power cord.
Remove the left cover and attach the laser optics positioning motor harness [A].
Close the left cover.
Plug in and turn on the main power switch.
Select [14: Trimmed area] in SP2-109-003, and then press [OK].
Press [Copy Window], and then print the test pattern in the copy screen.
- Check if the margin on either side on the output (14: Trimmed area) is less than 4±1 mm or not. If it is not within these limits, change the reference value (Bk) of the main scanning magnification adjustment (SP2-102-001 to -003).
- Adjust the values of the main scanning magnification only for Bk (black). It is not necessary to adjust other color’s values (cyan, magenta, yellow) because other colors are automatically adjusted in relation to the setting for Bk.
- Input the same value for each SP (SP2-102-001 to -003) even though there are three SPs of the main scanning magnification adjustment for the standard, middle and low line speed which are used for each paper type.
- Check if the margin on the left side on the output (14: Trimmed area) is less than 2±1 mm or not. If it is not within these limits, change the reference value (Bk) of the registration adjustment (SP2-101-001).
- Check if the margin on either side on the output (14: Trimmed area) is less than 4±1 mm or not. If it is not within these limits, change the reference value (Bk) of the main scanning magnification adjustment (SP2-102-001 to -003).

[*]PCU/DEVELOPMENT UNIT
Before Replacing a PCU
- In the PCU for MP C2504/C2004 and the PCU for MP C6004/C5504/C4504/C3504/C3004, the charging method is different. Variations in the charge voltage must be corrected when a PCU is replaced.
- Because of this, before replacing a PCU, do the procedure shown below. The main points are as follows.
- Input the charge voltage correction value for the new PCU.
- The machine will optimize SP settings related to imaging using process control, after you input the charge voltage correction value and replace the PCU.

Check SP2-005 to make sure that you have input the correct values. Check that they are the same as the values on the labels in step 2.
Turn the power OFF.
Replace the PCU.
Turn the power ON. (Process control is done automatically.)
- If you replace the PCU without inputting the correction value, do the following procedure:
- Case 1: When you set SP3-701 to “1”
- Input the PCU correction value.
- Execute process control manually with SP3-011-001 in order to adjust the machine settings with the PCU correction value.
- Case 2: When you did not set SP3-701 to “1” 1. Set SP3-701 to “1”.
- Case 1: When you set SP3-701 to “1”
- If you replace the PCU without inputting the correction value, do the following procedure:
- Input the PCU correction value.
- Turn the power OFF. Note that process control will start automatically.

- When holding the development unit, be sure to obey the following three DO NOTs:
DO NOT touch the development roller housing [A]. Doing so will deform the development roller housing, which causes the development roller to be scratched.
DO NOT touch the doctor blade . The doctor blade is an extremely sharp-edged blade, made with a high precision to work properly. So touching the blade causes physical injury as well as deformation of the blade assembly which causes a malfunction of the development unit.
[*]DO NOT touch the development roller. Doing so develops a fingerprint on the paper.
[*]Hold the development unit as shown below:
[*]When separating the PCU and development unit, the drum may come off and this
could cause a toner spillage. Hold the PCU [A] with the drum side up as shown below to prevent toner spillage.
Notes for Assembling PCU/Development Unit
Pay close attention not to spill any toner on the charge roller when assembling.
[*]Remove the heat seal [A] after replacing the PCDU.
[*]Remove the cap pasted on the toner port when replacing the PCDU.

[*]Before you remove or attach the image transfer belt unit, open the right door and the paper transfer unit.
[*]Do not touch the rollers but hold the upper/lower resin parts [A] when you lift the Image Transfer Unit. Touching the rollers may cause poor image quality.
[*]Precautions when attaching the image transfer belt unit:
- Slowly push the unit until it is inserted all the way, and then give a final strong push one more time. Then lock the ITB lock lever and ITB contact lever.
If the ITB contact lever is locked with the image transfer belt unit not fully inserted into the machine, the paper transfer roller is not set in the correct position when the
paper transfer roller unit is closed. This causes shadows on the image or paper jam, and the paper transfer roller unit may not open.
