Causes: • Check the scan-cover is not open. • Check shading profile. • Check white/black reference voltage in Main PBA. • Check the CCD lamp is on when scanning.
Remedy: • Ambient light can cause image problems • Remake shading profile in the Tech mode. • Replace Main PBA if it is defective. - U16-97 = 3.3V - U16-98 = 3.3V - U16-99 = 1.5V • If the CCD is defective, replace it. - CN3-19 is 5.8V when white original copying for R, B and 3.5V for G.
Code: 02
Description: Black copy
Causes: • Check for CCD problem in Main PBA. • Check shading profile. • Check the CCD problem in Main PBA
Remedy: • Check the CCD harness contacts. • Remake shading profile in the Tech mode. • If the CCD is defective, install a new ELEC/MECH-SCANNER MODULE, PL 2-2-21. - Cn3-19 is 7.3V when idle for R, B, and 5V for G.
Code: 03
Description: Defective image quality
Causes: • Check shading profile. • Check the gap between original and scanner glass. • Check printing quality.
Remedy: • Remake shading profile in the Tech mode. • A gap greater than 0.5mm can cause a blurred image. • See “Print” troubleshooting.
Code: 04
Description: Abnormal noise
Causes: • Check the scanner glass and any mechanical disturbance. • Check the motor driver in Driver PBA.
Remedy: • Check the scanner glass is correctly located and clean, check that the CCD carriage moves smoothly. • If any driver is defective, replace the main PBA. - U55 or U55-1, 15 = 0V to 24V swing signal when operating.
Code: 05
Description: Scanning error
Causes: • Check the printer cable. • Check how TWAIN driver is installed. • Check harness contact. • Check the IEEE1284 signal level.
Remedy: • Check correct installation, and use standard IEEE1284 cable. • Remove any other scanner driver. • Reboot after reinstallation of the TWAIN driver. • Check CN14 contact in Main PBAl. • If any signal level is defective, install a new Main PBA. - U36-66-74 in Main PBA = 0.8V to 2.4V TTL signal. • If necessary, install a new PBA MAIN MAIN, PL 1-19
Code: 06
Description: Defective image quality
Causes: • Check shading profile. • Check the gap between original and scanner glass.
Remedy: • Remake shading profile in the Tech mode. • A gap greater than 0.5mm can cause a blurred image.
