AR-SP8/RP8  UNPACKING AND INSTALLATION  2 - 3

11) Attach the SPF/RSPF to the copier.

Attach the SPF/RSPF by inserting the hinge guide sections of the
SPF/RSPF into the hinge guides L and R.

12) Insert the power plug into the outlet and turn the main switch of the

copier to the "ON" position.

13) Perform SIM setting.

• In the case of AR-SP8 (SPF)

Execute test command [2] of [26] and enter [1].

• In the case of AR-RP8 (RSPF)

Execute test command [2] of [26] and enter [2].

14) Carry out automatic adjustment of SPF/RSPF scanning position.

Use a black sheet and execute test command [53]-[08] to carry out
automatic adjustment of SPF scanning position.

For details, see the service manual.

15) Adjust the floating detection level of AR-SP8 (SPF) / AR-RP8

(RSPF).

Close the SPF/RSPF and use test command code [41]-[06] to
adjust the floating detection level of SPF/RSPF.

For details, see the service manual.

16) Check the copy ratio, and then check the center displacement and

leading edge image void.

Place an original on the document glass and make a copy. 

Then, place an original in the document feeder tray and make a
copy.

If the center of the copy from the document glass is displaced from
the copyfrom the document feeder, adjust the center referring to
the service manual.

AR-SP8/RP8  OPERATIONAL DESCRIPTIONS  3 - 1

It automatically copies up to 30 sheets of documents of a same size.
(Only one set of copies)

(RSPF)

(SPF)

1) When SPPD is ON (document remaining) when the power is

turned on.

2) When SPPD is not turned ON within about 1.5 sec (at 100% copy)

after starting the document feed operation.

3) When SPPD is not turned on within about 4.7 sec (at 100% copy)

after turning on SPPD.

4) When the SPF document jam release door or the OC cover is

opened during document transport (SPF motor rotating).

RSPF (SPF) open/close detection (book document) detection is per-
formed by detecting the interval between the reference lines on the
white Mylar attached to the paper exit guide (document scanning sec-
tion) by the scanner (CCD) and detecting the varied quantity.
