Opps sorry I mixed up the scanner model on LS-600 one I038404-00 (5V power supply) and I038405-00 (24V power supply). Both of them need to be checked FIRST I would suggest. see below

check the 24V and 36V outputs from the 2 rectangular power supply PCBs at the back of LS-600 scanner . .

thank you very much for teaching

I was talking different colorimeter model from their sticker on Noritsu QSS machines,,, I have no idea the Noritsu colorimeter used in Fujifilm LP7700 model

I saw CS-CM1000_blank,,,, CM1000 M, N, P, Q, R or S suffix Noritsu Colorimeter unit . . . . i have no definite answer to your question but I believe so.

contrast issue now

is your "red spots" photo look similar to this ? ? ... (from my photo collection)

Prior seeing your spots photo. . . I would like to place a bet your problem is "Magenta raindrops" symptom that you needs to replace your Green Laser gun. Temporary replacing a AOM Driver for Green could help / solve the symptom for a while ... later on symptom will come back again.... Would like to see your said "Red sports" photo. Happy Easter to all members . . . WEAR MASK !

could be swollen Left and Right ROLLER UNIT Z009020-01 at CD Rack entrance area see this

check also if you have a tight CD rack, take it out and try manually turn it with bare hand,,, also insert one leader to see the leader transport on CD rack assuming all those vertical gears are lined up properly ( the gears TIMING correct )

. . The clicking area is between . . the white gear ,,, part no. A229834-01 a two layer gear the black worm gear (underneath A229834-01 ) part no. A231340-01 or a broken bearing block (holding the machine main drive shaft) part no. A230433-00

I would say... 1) are Left & right Clamping solenoids working ? when you insert leader, solenoids are coming down to help the LEADER PUSH.. 2) Are square holes on leader in good shape? 3) Leader could be too soft IF THEY ARE CHINA MADE .. 4) LASTLY from video I saw "clicking gear" could be the wearing out of the horizontal black "worm gear" -AND- the clicking white gear . . . . Good Luck !

what model printer is yours, DirtNation ? you said you have some printers... is error happened on more than one pinter?
