These settings apply to plain paper, recycled paper, punched paper, pre-printed paper, letterhead paper, coloured paper, and user type paper.
You can select "60g/m2 to 89g/m2" or "90g/m2 to 105g/m2" ("16 to 23 lbs." or "23+ to 28 lbs.").

- Be sure to use only paper that is in the same weight range as the weight range set here. Do not mix plain or other paper that is outside the range with the paper in the tray.

### Registration Adjustment

Various devices mounted on the machine can be set.
If the colours are out of place on the printed surface when colour printing is performed, the print positions of the colours can be adjusted.
Tap the [Auto Adjustment] key to adjust the exposure. A message appears when the key is tapped. Tap the [Execute] key.

### Optimization of a Hard Disk

Various devices mounted on the machine can be set.
This function optimizes the hard drive of the machine by defragmenting data. If a job is in progress, a message will appear and optimization will not begin until the job is finished. During optimization, the following operations are not possible:

- Access to Setting mode (Web version), and reception of print data
- Use of keys on the operation panel
- Turning off the power with the main power switch of the machine.
- Auto Power Shut-Off

When optimization is completed, the machine will automatically restart.
When the document filing function is frequently used and output of files seems somewhat slow, optimizing the hard drive may improve performance.

### Fusing Cleaning Mode

Use this function to clean the machine's fusing unit when dots or other dirt appear on the printed side of the paper. When this function is executed, "V" printed paper is output and the fusing unit is cleaned.
If improvement is not noticed after the first time you use the function, try executing the function again.

### PTC Cleaning Mode

This machine periodically executes automatic cleaning and normally it is not necessary to execute this mode. Only in case, however, that coloured lines (linear colour unevenness) appear on the printed paper, execute this mode.

### MC Cleaning Mode

This machine periodically executes automatic cleaning and normally it is not necessary to execute this mode. Only in case, however, that black or coloured lines (linear colour unevenness) appear on the printed paper, execute this mode.

- Do not use this function when no black or coloured lines appear. Using this function under the normal condition may cause deterioration of the cleaner.
