• Reboot after reinstallation of
the TWAIN driver.
• Check harness contact.
• Check CN14 contact in Main
PBA
• Check the IEEE1284 signal
level.
• 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
Defective image
quality
• Check shading profile.
• Remake shading profile in the
Tech mode.
• Check the gap between original

any mechanical disturbance.
• Check the scanner glass is cor-
rectly located and clean, check
that the CCD carriage moves
smoothly.
• Check the motor driver in Driver

• If any driver is defective,
replace the Main PBA.
- U55 or U56-19 = 0V to 24V
swing signal when operating.
