This section explains how to resolve the problem of insufficient toner fusing on printed copies.

  • To adjust the following settings, pre-register the type of paper in use as a custom paper. For details see “3. Custom Paper Settings for Administrator” in the TCRU “Adjustment Item Menu Guide”.

Changing the fusing temperature or changing the process speed may produce one or more of the following side effects:

  • Paper curling
  • Paper misfeeding
  • Blisters
  • Glossy lines
  • Change of gloss

If one or more of the above side effects occurs, adjust the fusing temperature and process speed by decreasing the fusing temperature and increasing the process speed.

Solution:

Carry out the following sequence of procedures. Terminate the sequence as soon as the problem is resolved.

Procedure (a): Changing the fusing temperature

  1. In Advanced Settings for the custom paper in use, select Fusing Heat Roller Temperature Adj and increase the temperature by 5°C. (SP1-850-001 to 100: Htg Roller Temp Setting Custom Paper 001 to 100)

  2. Print the image and check toner fusion. Is the problem resolved?

    Yes

    Finished!

    No

    Increase the temperature an additional 5 °C.

  3. Repeat Step 2 until the temperature reaches 185 °C. Is the problem resolved?

    Yes

    Finished!

    No

    Go to the next step.

  4. Check the type of your machine. Is it Pro 8200S?

    Yes

    Consult the product specialist.

    No

    Perform Procedure (b) below.

Procedure (b): Changing the process speed

This procedure is available only for Pro 8220S/8220Y and Pro 8120S/8210Y. This will slow down the printing to give the toner more time to fuse. However, because of this, throughput will be reduced.

For example, when printing on A4/LT paper:

Pro 8220S/8220Y

  • If the process speed is changed from High to Middle: 136 cpm to 111 cpm
  • If the process speed is changed from Middle to Low: 111 cpm to 96 cpm

Pro 8210S/8210Y

  • If the process speed is changed from High to Low: 111 cpm to 96 cpm
  • Pro 8210S/8210Y does not have the Middle setting.
  1. In Advanced Settings for the custom paper in use, select Process Speed Setting. (SP1-852-001 to 100: Process Speed Custom Paper 001 to 100)
  2. Decrease the value by one level.
  3. If the present value is High, select Middle. If it is Middle, select Low.

  4. Print the image and check toner fusion. Is the problem resolved?

    Yes

    Finished!

    No

    If the problem persists, the machine may be faulty or the paper unsupported. Contact your service representative. The problem requires further investigation, so consult the product specialist.
