Well, it shows this screen

I do get a message saying (add paper) and the tray signals blink as I insert the paper trays. When I insert the paper trays, the machine makes the usual sounds.
mind-reader real.jpg I will keep thinking and send u some thoughts
One thought----can u print from the Bypass Tray
Good Troubleshooting requires u to follow a Procedure of Checks and Inspections & Re-Checks ---lessons learned a long time ago
Seems like SL 1 is the key to the lock (operation)
The lifter fails to move up (pickup from the cassette).
1. Releasing lever (for pickup roller).
Push in the releasing lever toward the rear. Does the descent movement of
the pickup roller stop?
NO: The releasing lever (spring) is displaced or deformed. Correct or
replace it.
2. Lifter gear retaining lever lock.
When the cassette is slid in, is the lock of the lifter gear retaining level released?
NO: Correct the locking mechanism of the lifter gear retaining lever or
replace it.
3. Lifter gear, Lifter gear retaining lever, Lifter ascent lever.
Is any of the gear faulty (damaged)?
YES: Replace it.
4. Lifter drive assembly.
Is the gear of the lifter drive assembly damaged or subject to foreign matter.
Is the drive belt faulty?
YES: Replace the gear/belt. Remove the foreign matter.
5. Pickup roller descent solenoid (SL1C).
Execute the following in service mode: code 6 of COPIER>FUNCTION>PART-CHK>SL; i.e., SL-ON.
Is the solenoid drive voltage present at J1604 of the pickup PCB? (J1604-4: 24 V, J1604-1:
PICKUPSL*)
YES: The pickup roller solenoid is faulty. Replace it.
6. Pickup PCB, DC controller PCB.
Execute the following in service mode: code 6 of COPIER>FUNCTION>PART>CHK>SL; i.e., SL-ON.
Is the solenoid control signal present at J302A-5 of the DC controller PCB? (J302A-5:
FDOWN_SL*)
YES: Replace the pickup PCB. ( Cassette pickup PCB )
NO: Replace the DC controller PCB.

Moving Up the Lifter
When the main power is turned on with the cassette set in the machine or the cassette is slid in while the machine is in standby state, the pickup roller shaft moves down to push
down the lifter trigger lever.
The cam is released when the pickup roller shaft pushes one side of the lifter trigger lever, and the drive from the main motor (M1) moves up the lifter.
When the cassette is slid into or out of the machine, the following takes place:
Moving Up the Lifter/Moving Down the Pickup Roller Shaft (cassette slid in)
1) Moving Down the Pickup Roller Shaft
With the power on, when the cassette is slid into the machine, the pickup roller moves
down until it comes into contact with the paper surface as follows:
• The cassette rear end pushes in the lever 1 of the pickup unit.
• When the cassette size detection mechanism goes ON, the main motor (M1) and the
pickup solenoid (SL1) go ON to swing the pickup lever.
Detecting the Presence/Absence of Paper Inside the Cassette
When the cassette runs out of paper, the paper detecting lever falls through the detecting hole of the cassette, causing the light-blocking plate linked to the lever to block the light of
the photointerrupter (Q1604 for cassette 1; Q1605 for cassette 2).

Yes I can print from bypass tray. The Motor M1 is working. These plastics should be transparent...
When I simulate the insert of a tray by hand, the lifter works fine with all the tooths, so it is doing contact. but the motor M1 is working. Not easy...

Hello teckat
So, finally i managed to get other working machine. today i´ve tried the pickup board PCB and this is not the problem. Tomorrow i´m going to try the pickup assembly and the DC controller PCB. Fingers crossed...
Hi people. So the problem was the Paper pickup assembly. It seems that when a spring snaps inside this assembly, the gears go crazy and it is not possible to sincronize them in the correct order. but now all is going good. Thanks you for your help.
