Excellent, fast delivery, excellent product. Good luck!

This manual is for the usa model only. But it is clear
, accurate and comprehensive, including board layouts and schematics.
I found it extremely useful for my mitsubishi dp-86da, but the same diagram would also work for the realistic lab5000 and hi fi 80. Thanks.

Great to have extra resources for Service Manuals, Now days you can really not trouble shoot efficiently without one , Wayne at IRIONS TV & ELECTRONICS REPAIR Clearwater , Fl. 33755 727-446-7955

For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.

Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe
IMAGE FUSING
17 May, 1999
Fluorescent Lamp Flicker
Starting and stopping the fusing lamp power every second causes fluorescent lighting in the room to flicker. To reduce this flickering, use SP1-108 to change the cycle from 1 second to 3 seconds. In addition, full power is applied to the fusing lamp gradually, not all at once. This prevents the power in the room from dropping suddenly. This feature is known as �Soft Start�. The machine does this by gradually allowing more power to the fusing lamp over a number of zero-cross cycles of the ac supply. The diagram below shows full power being applied gradually over the duration of 6 zero-cross cycles. With SP1-107, this number can be set to 6, 10, or 20.

Fusing Temperature Control for Thick Paper at the By-pass Tray
When thick paper mode is selected, the machine changes the target fusing temperature from 180°C to 190°C. This also happens when the machine detects A6 size. This is because the machine automatically assumes that the A6 paper is a post card, and post cards should be treated as thick paper.
Pre-heat Mode (Fusing Idling)
When the machine is powered on, or the right door is closed, the hot roller turns for 10 seconds. If the SP1-103 setting is 1 (Yes), when the fusing thermistor detects a temperature lower than 60°C, the hot roller turns for 60 seconds (instead of for just 10 s) after the machine is powered on, or the right door is closed. This maintains conditions for fusing copies made on thick paper during cold weather conditions.
To Prevent Offset when Making Multiple Copies on Small Paper
This prevents the temperature at the ends of the hot roller from being higher than at the center. If the smallest copy paper width detected during a one-minute interval is less than 220 mm, the machine lowers the target fusing temperature by 10°C. Then, during the next minute, if the smallest width detected is less than 220 mm again, the machine lowers the target temperature by another 5°C.
