General Procedures & Information
dC604 Registration Setup Procedure
Description
The dC604 routine places an internal generated scaled test pattern on the paper.
NOTE: ADJ 8.1 Registration Setup contains only a reference to this diagnostic procedure.
Purpose
To measure and adjust image to paper registration using the four routines:
1. Image Output Terminal Registration side 1 - simplex lead and top edge registration adjust-
ment.
2. Image Output Terminal Registration Side 2 (duplex) - duplex lead and top edge registra-
tion adjustment.
3. Scanner Registration - document glass lead and top edge registration adjustment.
4. DADH Registration - constant velocity transport (CVT) lead edge and centre registration
adjustment. Refer to dC502 DADH Width Guide Calibration.
NOTE: During the scanner and the DADH registration procedures a border erase is
applied to the copied test patterns. Since the test pattern has been designed for both mar-
kets regions, the size of the edge deletion will depend on the paper size:
• For A4 LEF paper, all edges have a 10mm deletion, but the bottom edge (Zone C on
Figure 1) will measure 28mm from the edge of the paper.
• For 8.5 x 11 LEF paper, all edges have a 10mm deletion, but the trail edge (Zone B
on Figure 1) will measure 16mm from the edge of the paper.
Initial Action
• Ensure that 8.5 x 11 or A4 LEF paper is loaded in tray 1.
• Ensure that the ROS is secured and positioned correctly. Check that the ROS securing
screw at the front of the machine is present and secure, refer to REP 6.1.
Procedure
NOTE: Always perform the IOT Registration Side 1 adjustments before performing any other
registration adjustment, as the IOT Registration Side 1 adjustment affects the others.
1. Enter diagnostics, GP 1.
2. Select, Diagnostics Routines, then select Copier Routines, then select dC604 Registra-
tion Setup Routine.
3. Select Image Output Terminal Registration Side 1, then select All Trays, then select Print
Test Samples and follow the UI screen prompts.
NOTE: Do not select individual trays unless directed by the documentation.
a. Compare the zones A and D on the test samples, with those in Figure 2.
b. Adjust the registration, enter the number on the scale at the edge of the paper.
For example. If the top edge of the paper aligns with the 20mm mark on zone A (20
mm indicates correct IOT registration, Figure 2) then enter 20mm. If the top edge
aligned with the 15mm mark then enter 15mm.
4. Select Image Output Terminal Registration Side 2, then select All Trays, then select Print
Test Samples and follow the UI screen prompts.
5. Select Scanner Registration and follow the UI screen prompts.
a. The first three copies out will be the IOT test samples, one of which will be used as
an original to make the scanner test samples.
NOTE: To obtain the correct scanner registration. Check that the registration on the
IOT test samples is correct, Figure 2. If not correct then return to step 3.
b. Place one of the IOT test sample on the platen glass.
c. Compare the zones A and D on the scanner test samples, with those in Figure 3.
d. Adjust the registration, enter the number at the point where the scale is deleted.
For example. If the top of the zone A scale is deleted at the 10mm mark (10mm indi-
cates the correct scanner registration, Figure 3) then enter 10. If the top of the zone
A scale is deleted at the 5mm mark then enter 5.
6. Select Document Handler Registration and follow the UI screen prompts.
a. The first three copies out will be IOT test samples which will be used as originals to
make the DADH test samples.
NOTE: To obtain the correct DADH registration. Check that the registration on IOT
test samples is correct, Figure 2. If not correct then return to step 3.
b. Place the IOT test samples in the DADH.
c. Compare the zones A and D on the DADH test samples, with those in Figure 3.
d. Adjust the registration, enter the number at the point where the scale is deleted.
For example. If the top of the zone A scale is deleted at the 10mm mark (10mm indi-
cates correct DADH registration, Figure 3) then enter 10mm. If the top of the zone A
scale is deleted at the 5mm mark then enter 5mm.
Place the IOT test samples in the DADH to enable the Save option.
7. If the correct registration can not be obtained because the registration scales are out of
range or off the page. Enter dC132 NVM Initialization, select Machine Variable NVM and
initialize. This will reset all of the registration values to default, return to step 3, complete
all four routines.
8. Take samples from each tray using the individual tray select button and check the lead
edge and top edge registration is within specification, Figure 2. If the top edge registration
is not correct on individual trays then go to step 9.
9. The individual trays can be adjusted to compensate for any mechanical variation between
the trays, which may cause an error in the top edge registration.
The individual tray top edge has an adjustment range of +/-10mm with increments of
0.5mm. When saved, the adjustment will update the NVM offset value for the specific tray.
To adjust the top edge registration on individual trays perform the following:
a. Enter diagnostics GP 1. Select, Diagnostics Routines / Copier Routines / dC 604
Registration Setup
b. Select Image Output Terminal Registration Side 1 / select the individual tray / Print
Test Samples.
NOTE: If the top edge of the paper aligns above the 20mm mark on zone A i.e. at
22mm. Then 2mm to align the top edge of the paper with the 20mm mark on
zone A. If the top edge of the paper aligns with the 15mm mark on zone A. Then
select -5mm to align the top edge of the paper with the 20mm mark on zone A.
Make the adjustments, then press Print Test Samples. When the top edge of the
paper aligns with the 20mm mark on zone A, the registration is correct, Figure 2.
Press Save and repeat the procedure as necessary for the other trays.
