the procedure (see Section 2.1.3). If this fails, try
ADVANCED ENTRY (see Section 2.1.4).
If the problem persists, it can be due to one of
following reasons:
1) The reflective marks may not be made of
carbon-based ink.
2) Possible debris in the Media Sensor; clean and
retry calibration (see Section 2.4.3).
3) The Media Sensor may be defective; replace it
(see Section 4.8).
4) The Main Logic PCB may be defective; replace it
(see Section 4.9).
Press any key to continue. Retry the STANDARD
