time as the progress bar on the LCD reached the point of about one-third of the whole length.
Cause
The 256MB option memory kit that should be connected to PS-T1 was mistakenly connected to the Main Controller PCB of this machine.
Field Remedy
When connecting a memory to PS-T1, connect it to DIMM1 socket (an inner socket) on the motherboard of PS-T1. On DIMM2 socket (an outer socket), a
standard 256MB memory is connected.

Reference: When connecting only the imagePRESS server-T1, there is no need to mount an expansion memory to this machine.
14.3.3.3.3 When Saddle Finisher-AA2 saddle-stitches 12x18 size papers, paper folding position does not align with paper
stapling position

[ Inspected by Canon Inc. ]
Description
When saddle-stitching 7 sheets of 12x18 size paper, the paper folding position did not align with the paper stapling position. In this inspection case, neither
the position displacement of printed image nor the same symptom with such size papers as 11x17, LGL, and LTR-R could be seen.
Cause
For 12x18-size paper, there was a fault in controlling the position of the paper positioning plate.
Field Remedy
If the version of the Suddle Controller PCB, SDL-STCH software is earlier than Ver. 4.01, update the software to Ver. 4.01 or later, and perform the same
job again. The SDL-STCH software Ver. 4.01 and later has modifications to the fault that the paper folding position shifts by about 0.25mm every time the
finisher unit performs the saddle-stitch operation.

[ Case in the field ]
Description
During copying, a paper jam suddenly occurred, and the error code "E748-4901" followed the power-off/on operation that was performed for solution to the
jam; then, this machine was shut down in the shutdown mode, and the main power switch was turned ON again. However, this machine failed to started up.
In this field case, the main power indicator on the control panel came on. When the same symptom occurs, go through the field remedy below.
- E748-4901 can be displayed when a drop in 3.3V (for emergency use) has been detected in the course of operation.
Cause
Since the red and blue lead wires extending from the drawer connector in the rear side of the fixing feeder assembly had been pinched, the safety circuit
worked.
Field Remedy
1. Slide out the fixing feeder assembly, and then turn on the main power switch.
2. If this machine is powered on normally, check if the lead wires from the drawer connector in the rear side of the fixing feeder assembly are pinched; if the
degree of pinching is too severe to be modified, replace the drawer connector.
Note: When attaching the drawer connector after modification of lead wires or replacement of drawer connector, be careful not to render the lead wires
pinched.
3. If it is found that the lead wires are not pinched in Step2, refer to the troubleshooting for E748-4901 in the service manual and replace the power supply
PCB and the DC controller PCB in this order.

14.3.3.3.5 Waste Toner Full Error (E013-0001) Displayed After Toner is Emptied from the Waste Toner Bottle
0014-3609
imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
1. Cause
When emptying toner in the waste toner bottle, it is possible that the residue toner adheres to the waste toner detection window inside the toner bottle. As a result,
the toner can be mistakenly detected to be full causing waste toner full error (E013-0001).
2. Remedy
Tighten the cap to the waste toner bottle. Tilt the bottle as shown in the picture below, and tap the detection window 4 to 5 times lightly with your fingers (See Note).
Attach the waste toner bottle onto the main body.
