3.2.2 Paper alignment at the registration roller
The aligning amount is adjusted by using the follow ing codes in Adjustment Mode (05).
Sub-code (*1) 0: Long size 1: Middle size 2: Short size 
(*2) 0: Long size 1: Middle size 2: Short size 3: P ost card
(*3) 0: Long size of OHP film 1: Middle size of OHP  film 2: Short size of OHP film
Notes: 
1. Long size: 330 mm or longer (13.0 inches or longe r)
Middle size: 220-239 mm (8.7-12.9 inches) 
Short size: 219 mm or shorter (8.6 inches or shorte r)
2. The adjustment of “Post card” is for Japan only.

(3) Perform the same procedure for all paper sources.
Note: Note:  When paper thinner than specified is used, paper ja ms may occur frequently at the registration 
section. In this case, it is advisable to change (or  reduce) the aligning amount.
However, if the aligning amount is reduced too much , this may cause the shift of leading edge 
position. So, when adjusting the aligning amount, t ry to choose the appropriate amount while 
confirming the leading edge position is not shifted .
* As a tentative countermeasure, the service life of  the feed roller can be extended by increas-
ing the aligning amount.
(2) Check if any transfer void is occurring. If 
there is a transfer problem, try the values in  
descending order as “31”   “30”   “29”··· 
until the transfer void disappears. At the  
same time, confirm if any paper jam occurs.  
Also, when the aligning amount has been  
increased, this may increase the scraping 
noise caused by the paper and the Mylar  
sheet as it is transported by the registration  
roller. If this scraping noise is annoying, try to  
decrease the value.
