Some of the pictures in this manual are a bit irritating. I had to dissassemble the unit and some of the screws have different threads, which is not mentioned in this manual. Also some of the drawings of the boards look different than the actual boards.
After all, the manual was very useful. I was able to recalibrate the capstan drive and it is working fine again.

This manual is very good. 303 pages scanned in a very high resolution. My camera has bad, leaking capacitors which all of the V5000 models are suffering from these days.
There is a huge part list with all capacitors, transistors etc. in this manual which helped me a lot. Otherwise I would not have been able to buy replacement parts.
The dissassembly guide is very enormous and detailed. Unlike on the Panasonic MS1 manual I downloaded here it actually looks like the real parts look. And the screws are labeled correctly, so you shouldn't have any left after the repair. ;)

has all the schematics you could need,and very well laid out format also has all part numbers along with an exploded view which is helpful

Very nice to have! Now it is no problem to understand how it is put together.
Helps me a lot.

good scans, all is clear. all pages in order. recommended
Circuit Description
3-8-4-2. The Concept of Fixed Lamp Control For �xed lamp control, the logic unit "fuser on" control signal and SMPS unit DC power must be supplied. This circuit turns on only when "fuser on" sends the signal and the DC power is supplied. The following explains how the �xed lamp control circuit works. logic unit "fuser on" sends trigger current to triac driver PC3 LED, then the infrared ray is detected by PC3 photo detector. Next, YC3 triac is conducted. The conducted current sends trigger input to triac SY1 gate. At this point, SY1 is conducted and AC power is supplied to �xed lamp. Lamp is turned on and temperature rises. As this �xed lamp control circuit uses the AC voltage ("+" and "-" are repeated) as the power supply, it used two-way triac (SY1), which has advantage over one-way SCR considering the price, size and reliability. Triac's gate can be triggered by either forward or reverse signal. Once triac is turned on, it will not be controlled by gate signal, but will be continuously on until the current between major terminals decreases below the holding current. In other words, you cannot turn it off with reverse signal unlike SCR. This property is called current-voltage threshold rise rate (commutation: dv/dt). In AC power control application, triac has to turn off conduction in each zero crossing or switch it twice in each cycle. This switching operation is called commutation. It is possible to turn off the triac at the end of half cycle by eliminating the gate signal when the load current (IL) is gained at the level equal to or lower than holding current. When triac commutes off-line, the direction of the voltage of the both ends of triac will be reversed and increase up to the maximum value of line voltage (VAC). At this point, the width of rise rate will be determined by dv/ dt and overshoot voltage, by the circuit. When triac commutes off-line, the voltage of both ends of triac will have the same voltage as the line voltage.
