Face-Down Delivery Slot Stationary JamThe CPU will identify a face-down delivery slot stationary jam if the paper does notmove past the face-down tray delivery sensor (PS11) within a specific period of time (T)after the face-down tray delivery sensor (PS11) has detected the leading edge of thepaper.T = about 2.4 sec (normal, A4)T = about 4.1 sec (normal, A3)T = about 9.4 sec (transparency, A4)T = about 16.6 sec (transparency, A3)T = about 7.0 sec (thick paper, A4)T = about 12.4 sec (thick paper, A3)8. Delivery Excess Length Feeding JamThe CPU checks the size of paper using the registration paper sensor (PS1), and willstop the printer unit operation if the difference in size between the the result of its detec-tion and the result of later detection is +15 mm or more. If the difference is between +7.5and 15 mm or -3.7 mm or more, it will discharge the paper as a paper size mismatch.9. Non-Default Size Feeding JamIf the transparency sensors 1 and 2 detect a transparency not of a specific size, anon-default size feeding jam is identified.10. Door Open JamIf any of the following sensors detects paper when the cover is opened/closed, theCPU will identify a door open jam:• Registration paper sensor (PS1)• Pick-up assembly paper sensor (PS17)• Separation sensor (PS5)• Face-down tray delivery sensor (PS11)• Fixing delivery sensor (PS1903)11. Inside Residual JamThe CPU will identify an inside residual jam if any of the following sensors detectspaper when the paper switch is turned on:• Pick-up assembly paper sensor (PS17)• Separation sensor (PS5)• Face-down tray delivery sensor (PS11)• Fixing delivery sensor (PS1903)CHAPTER 5 PICK-UP/FEEDING SYSTEM5-31Download free service manual at http://printer1.blogspot.com
