Troubleshooting Paper Abrasion and Blurry Images (Head Height)
The Printhead height setting affects printing quality.
Specifying a low Printhead height makes images clearer and enhances printing quality but may cause paper to rub against
the Printhead.
On the other hand, specifying a high Printhead height will prevent paper from rubbing against the Printhead but may reduce
the printing quality.
Important• Paper  rubbing  against  or  becoming  caught  on  the  Printhead  may  jam  or  result  in  printed  documents  that  are
soiled.Note• Raise or lower the printhead, depending on the nature of the problem.

played (to the right of  Automatic ) once you select the type of paper currently supplied.
However, the value is cleared when the printer is turned off or the paper is replaced.
5. Press  ▲ or  ▼ to select  Head Height , and then press the  OK button.
6. Press  ▲ or  ▼ to select the desired setting value, and then press the  OK button.
Note•Using  Automatic   will  ensure  that  the  printer  adjusts  the  Printhead  height  to  the  optimal  level  before
printing, accounting for the ambient temperature and humidity. When a setting other than  Automatic
is used, that value will always be applied.
• Depending on the type of paper, some setting values may not be available.

Adjusting the Feed Amount
If printed documents are affected by the following problems, try adjusting the feed amount. •Banding in different colors
• Line length is not accurate in the direction paper is fed
To adjust the feed amount, do the following, in this order.
1. Depending on the issue, adjust  Adj. Priority to suit the particular type of paper.
 (See " Selecting a Feed Amount Adjustment Method (Feed Priority) .")
→P.845
2. Execute  Adj. Quality  or Adjust Length , depending on the selection in  Adj. Priority.
 (See " Automatic Banding Adjustment (Adj. Quality) .")
→P.846
 (See " Manual Banding Adjustment (Adj. Quality) .")
→P.848
 (See " Adjusting Line Length (Adjust Length) .")
→P.850

 (See " Fine-Tuning the Paper Feed Amount (Adj. Fine Feed) .")
→P.850
Selecting a Feed Amount Adjustment Method (Feed Priority)
Methods of adjusting the amount paper is fed are set in  Adj. Priority.
Adjust  Adj. Priority  to suit your particular printing application.
• Print Quality  : Adjusts the feed amount to reduce banding across the sheet in printed documents.
Adj. Quality  settings are applied. When  Adj. Fine Feed is executed, the  Adj. Fine Feed settings are applied in addi-
tion to the  Adj. Quality  settings.

Automatic Banding Adjustment (Adj. Quality)
If printed images are affected by banding in different colors across the sheet, execute  Adj. Quality for automatic adjustment
of the paper feed amount.
There are two modes of automatic adjustment to correct banding:  Auto(GenuinePpr) and Auto(OtherPaper) . In either
mode, the printer prints and reads a test pattern for automatic adjustment of the feed amount.
• Auto(GenuinePpr)Use this mode with paper identified in the Paper Reference Guide.
 (See " Types of Paper .")
→P.768

							• Auto(OtherPaper)Use this mode with paper not in the Paper Reference Guide, or if  Auto(GenuinePpr) does not eliminate banding.
 (See " Types of Paper .")
→P.768
Note•Always check the  Adj. Priority values before using  Auto(GenuinePpr) or Auto(OtherPaper) .
 (See " Selecting a Feed Amount Adjustment Method (Feed Priority) .")

• Adjustment  is  not  possible  with  Auto(GenuinePpr)  and Auto(OtherPaper)  when  using  highly  transparent
media.
In this case, use  Manual adjustment.
 (See " Manual Banding Adjustment (Adj. Quality) .")
→P.848
• If  additional  fine-tuning  is  necessary  after  Auto(GenuinePpr)  and Auto(OtherPaper) ,  execute Adj.  Fine
Feed .

→P.850
• Use  Adjust Length  to ensure that lines in CAD drawings are printed at exactly the right length.
 (See " Adjusting Line Length (Adjust Length) .")
→P.850
• This may take some time, depending on the type of paper.
• Use paper of the same type and size for adjustment as you will use for printing.
