This adjustment has to be performed for each paper source.
The following table shows the order of the paper source to be adjusted, code, paper size and accept-
able values.
Order for Paper

1 Lower
drawer
2 Upper
drawer
3 PFP or LCF
4 Bypass feed
5 Duplexing
While pressing [0] and [5] simultaneously, turn the power ON. → (Adjustment Mode)
(1)
Press [1] ([3] for duplexing) → [FAX]. (A grid pattern with 10 mm squares is printed out.)
(2)
(3) Measure the distance D from the leading edge of the paper to the 6th line of the grid pattern.
* Normally, the 1st line of the grid pattern is not printed.
* At the duplexing, measure it on the top side of the grid pattern.
(4) Check if the distance D is within 52±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance D again.
<Procedure>
(Adjustment Mode) → (Key in the code shown above) → [START]
→ (Key in an acceptable value shown above)
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed
→ Press [1] ([3] for duplexing)
→ [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance D becomes (approx. 0.2 mm/step).

Adjustment for long-sized paper

While pressing [0] and [5] simultaneously, turn the power ON. → (Adjustment Mode)
(1)
Press [3] → [FAX]. (A grid pattern with 10 mm squares is printed out. Use A3/LD from the lower
(2)
drawer.)
(3) Check the grid pattern on the test print and measure the distance E from the left edge of the
paper to the 6th line of the grid pattern.
(4) Check if the distance E is within 52±0.5 mm.
(5) If not, use the following procedure to change values and measure the distance E again.
<Procedure>
(Adjustment Mode) → (Key in the code [498]) → [START] → [0] → [START]
→ (Key in a value (acceptable values: 0 to 255))
→ [ENTER] or [INTERRUPT] (Stored in memory)
→ "100% A" is displayed.
→ Press [3] → [FAX] → (A grid pattern is printed out.)
* The larger the adjustment value is, the longer the distance E becomes (approx. 0.04 mm/
step).
