5170 DN What is the proper setting for the adjustable screw to the left side of the fixing unit, when the cover is removed from the back? This screw seems to be spring loaded, and was not fully tightened when I removed the covers for a good cleaning.

Fist you need confidence.. then only you try it.. no video/manual for this, because of its no suggestible. Read once again & once again understand it then try it..

Open back cover & side covers.. two boards you will found at back side left one is formatter & right one DC controller. remove both DC & formatter, mark the connectors where you removed.
Remove the plate where DC & formatter placed,after that only you will find the scanner assm.
Two screws only protected to scaner assm, mark them where you removed.
Scanner assm: While cleaning the scanner assm must be wear glows..to avoid finger prints.
Remove the scanner assm cover(two screws) & shutter. Observe two motors with four reflecting mirrors, clean the mirrors & engine reflector sides(a squared metal part which was rotates along with the motor) with ear buds gently. ( ear buds are good cleaning method) while fixing the unit back ensure that seated properly.. fix back every thing & do calibration.. check the print quality, if you failed to fix the scanner unit in properly, you need to do entire things once again.. Good luck..

that is code for damaged fixing film u will need a technician to replace the fixing film. or replace fixing unit( for that, open the front cover; open screw of down left side small cover, remove cover; detach connection on the upper left side.remove earthing screws and in the upper centre, fixing unit mounting screw. release feeder leaver oin right side.open left door, slide out fixing unit replace with a new one and revert whole process.)

passenger side of the car, under the dash board

most likely the drum popped out.
open the left side cover and remove the waste toner bottle..seated just above the waste toner bottle..press on the drum unit that sits above it..you will here it pop back into place .. if you hear it snap back it simply power off than back on printer....
if the drum is seated correctly.. than you need to replace the drum unit

Platen Gap Adjustment (Figure 35)
IMPORTANT Only do this procedure if the original equipment shuttle frame assembly or platen has been replaced by a new or
refurbished unit.
1. Prepare the printer for maintenance (page 338).
2. Remove the shuttle cover assembly (page 357).
3. Loosen the platen open belt (page 415, steps 2, 3, and 4).
4. Raise the forms thickness lever (1) to the fully open position.
5. If you are adjusting any model except the 6400-i20, select a 0.011 inch (0.28mm) flat feeler gauge.
If you are adjusting a 6400-i20, select a 0.012 inch (0.30 mm) flat feeler gauge.
ATTENTION Do not force the platen against the feeler gauge. Damage to the hammer tips will result.
6. Insert the feeler gauge (2) straight down between the hammer bank cover plate (3) and ribbon mask (4), within four
hammer positions of the left end of the hammer bank.
ATTENTION Adjust the platen set screws less than 1/4 turn on one side, then check the other side. Adjustment sensitivity is
approximately 0.03 inch per revolution of the set screw. Also, insert the feeler gauge no more than two inches down
from the top of the ribbon mask.
7. Gently close the forms thickness lever (1). As the platen is closing, gently slide the feeler gauge up and down, keeping it
between the hammer tips and ribbon mask. If the feel is too tight as the platen closes, adjust the 3/32 inch set screw (5)
counterclockwise. If the feel is too loose, adjust the set screw clockwise. With the forms thickness lever closed all the way,
the feeler gauge should contact both the tips and the ribbon mask and move with light friction. Shift the gauge slightly to
verify.
8. Repeat steps 4 through 7 at the right end of the hammer bank.
9. After adjusting both sides, check the gap again at both ends. Readjust if necessary.

Hi

Error E50 comes up on the printer when there is an issue with the fuser unit of the printer. It is either the fuser unit is faulty or fuser unit is not clean. This what you can do to get the error fixed--

All "left" and "rights" are when facing the front of the printer. Remove the electrical cord from the back of copier by pulling. Remove bottom tray. Remove the smaller tray that comes out the back that has a LTR/A4 lever. Open front of machine to take out toner and drum just to make it lighter. Leave open. Take off top cover (4 screws and two wire jacks to unplug). Remove screw on back right side near bottom. Remove screw on front left near bottom that holds left side cover. Remove screw on back left near bottom (it holds a piece in the back and the side cover). Slightly pull out that back, left plastic piece (it won't come out all the way yet) and wiggle things around to get the left side cover off. That back left piece that didn't come out all the way has a plastic *** holding it in. To be able to press that *** is why the side cover is removed. Press *** and pull the back left piece out while wiggling things around to get the 3 plastic pieces in the back to all come out. This exposes the fuser. Remove the two wire jack connections. Remove the two screws holding fuser in. One of those screws is big with a spring - don't worry, the spring stays in place. The other screw looks normal, but it is a little longer than the other screws so remember where you lay it. Find the 2 black wires on the fuser leading to the problem piece. Remove the single screw holding it in. Pull it out and clean the wire connections. Now put things back together.

And after this is done reset the printer by--

Switch the machine on. Wait until the yellow data light goes out. Now hold down the 'GO' button AND the '+' button together four about four seconds. The LCD panel will now display a 'RESET COMPONENT LIFE' message. Use the + and - keys to select the fuser unit, and reset it. Turn the printer off. Turn it on again and it will work. Now reset the drum counter , and also the toner cartridge counter in the same way.

Please accept the solution and revert for further assistance.

Thanks

1. See the ugly red color bands on the television set? These can also occur in blue and green. We're going to fix these!

2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.


3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.


5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.


6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.


7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

I do not know what you mean by clear tape or sponge strip but if by ridged you mean what i think then yeah we are pretty much taking about the rubber band that moves the carriage.

So it got off, huh... it normally happens when someone pulls way too hard the cartridges, anyways, if it got loosen from the right side you need to remove all covers and scanning unit.

to do this please remove the screws on the back side and then remove the black front covers, they are set by pressure on (and some plastic nails) so i recommend you to use a flat screw driver and gently pull. look up for little triangular marks or the plastic nails, any good pressure point. once those black covers are removed, unscrew the screws (i dont know if that's the proper expression sorry) you see and proceed to remove the plastic covers, they should come out easily. then you might not need to remove the scanning unit IF you actually can set the band on again. It goes around a little gear you can actually move towards your left to avoid stretching the band more than needed. good luck!!
if you nee dto remove the scnaning unit please unplug everything on the left side before. should be at least two flat cables and a few others.
