COPYRIGHT © 1999 CANON INC. CANON 660/2100 REV.0 FEB. 1999 PRINTED IN JAPAN (IMPRIME AU JAPON)1. Pick-Up Delay Jam 1The CPU will identify a pick-up delay jam 1 if the print paper does not reach the pick-up assembly paper sensor (PS17) a specific period of time (T = about 2.7 sec) after thevertical sync signal (TOP*) has been generated.2. Pick-Up Delay Jam 2The CPU will identify a pick-up delay jam 2 if the paper does not reach the registra-tion paper sensor (PS1) a specific period of time (T) after the horizontal sync signal(TOP*) has been generated.• T = about 2.9 sec if the multifeeder tray is used.• T = about 3.3 sec if a source other than the multifeeder tray is used.3. Wrapping on the Intermediate Transfer DrumThe CPU assumes that the paper has wrapped around the intermediate transfer drumif the separation sensor (PS5) does not detect the paper within a specific period of time(T) between 1.5 and 8.7 sec after the registration drive signal (TOPR*) has been gener-ated.T = about 0.1 sec (normal mode)T = about 0.4 sec (transparency mode)T = about 0.3 sec (thick paper mode)4. Fixing Delivery Delay JamThe CPU will identify a fixing delivery delay jam if the paper does not reach the fixingdelivery sensor (PS1903) within a specific period of time (T) after the registration drivesignal (TOPR*) has been generated.T = about 3.2 sec (normal mode)T = about 12.8 sec (transparency more)T = about 9.6 sec (thick paper mode)5. Fixing Delivery Stationary JamThe CPU will identify a fixing delivery stationary jam if the paper does not move pastthe fixing delivery sensor (PS1903) within as specific time (T) after the sensor has detect-ed the leading edge of the paper.T = about 2.4 sec (normal mode, A4R)T = about 4.1 sec (normal mode, A3)T = about 9.4 sec (transparency mode, A4R), T = about 16.6 sec (transparency mode,A3)T = about 7.0 sec (thick paper mode, A4R), T = about 12.4 sec (thick paper mode,A3)6. Face-Down Delivery Slot Delay JamThe CPU will identify a face-down delivery slot delay jam if the paper doe not reachthe face-down tray delivery sensor (PS11) within a specific period of time (T) after the fix-ing delivery sensor (PS1903) has detected the leading edge of the paper.T = about 4.0 sec (normal mode)T = about 16.0 sec (transparency mode)T = about 12.0 sec (thick paper mode)CHAPTER 5 PICK-UP/FEEDING SYSTEM5-30Download free service manual at http://printer1.blogspot.com
