first clean the inside of the printer as there might be tiny strips of paper that cling to the print head assembly, second open the scanning area and clean the camera as tiny lines came from dust that was being read by the camera as an image.
If your printer does not have a duplex unit then the printercannot print double sided pages automatically. You can print double sided pages but you have to do it one page at a time. First print Page 1 then place the page back into the paper tray, but turn thepage upside down and the print Page 2. Then print page 3 on one side then page 4 on the other side and repeat for therest of the document. I suggest you try a test page first, to get the printing the right way up onboth sides of the page so it reads correctly.
press function 6-4 start and let that print .. if you have no lines then the machine is the scan glass..
to clean scan glass open the control panel door but not the toner door.. you will see 2 green plastics on either side of the machine.. press them both towards the center and lift..when done properly you will lift the white plastic plate about a 1/4 inch.. tilt that up and clean the glass with windex or alcohol..
if this does not work you need a tech because you scratch the glass
THe main problems are toner spill form drom/dev units ..the transfer on the right hand door will have to be emptied every few months. the paper tray paper stops need to be checked as they come out of place and cause paper jams if not set in place..cahrge rollers can be troublesome if not cleaned every coulple of months and may cause dirty image at the sides or lines on copies..dust on laser **** glass can cause faint on sides of copies.. the fuser stripper fingers tat guide the paper need to be checked for toner under the points to stop paper jams in fuser and the lower guide plate entrance to the fuser needs to be cleaned off every now and then to stop crinklin of paper...apart from that good machine
1. Open the front door you did
2. Open the clips at the hinge housing (2) on
the right and left hand sides of the front
door by lifting them up. you did
Hold the door onboth sides and then close the door and lift
the door up to remove it. assume this is what you did. Refitting is the reversal of removal.
There are 2 primary paper sensors. One is the registration sensor where the paper feeds in, the second is associated with the fuser unit.
The first sensor is located under a cover under the transfer unit. i) Open the door ii) Lift out the transfer unit (Q3964A) iii) Locate the black plastic cover plate with a small green flap in the centre. This assembly is directly under where the transfer unit was installed. iv) There are 2 shiny screws that secure this cover plate. Carefully remove these screws. v) Lift out the black cover plate by lifting the left section up first which allows the right section to come clear of gears. vi) Check for paper obstructing the small movable lever under the cover plate.
vii) To reinstall the cover plate, insert the right hand side down first and line up with the mounting holes.
The black spots mean you either need a new imaging
drum, transfer kit or fuser. You'll have to print some stuff and try to
catch where the black marks are appearing. Try this method (it's called
a Half-self test)
Load 2 -3 sheets of letter paper in tray one (manual feed) and remove paper from the rest of the trays. From the information menu, request a demo page The
MOMENT the tail end of the paper disappears into the printer, open the
right door. Open the front doors and release the levers for the imaging
drum and the transfer drum. Carefully remove both pieces and examine
You should find the paper partway on the
transfer belt but not in the fuser. If you see black marks here, start
with the imaging drum. Open the shutter that covers the sea green shiny
roller and look for marks on the drum (you'll see build up on the
edges, that's normal, you should not see any scratches, pockmarks or
toner on the center of the drum). If it looks clear, take a look at the
transfer drum for marks or cuts on it's surface. (note: the transfer
drum can be cleaned off with a dry lint free cloth, do not touch the
shiny sea green roller of the image drum)
If everything looks
good there, then likely the black marks are coming from the fuser. Let
the printer sit, turned off for about half an hour to allow the fuser
to cool. You can then remove the fuser and look at the rollers to see
if there is any build up or damage there.
If you are not
seeing any obvious issues with any of these parts, then start with the
imaging drum. If you know that any of these parts have never been
changed, then change them as they do have a limit to how many pages and
how much time they can be used for.
Hi there check that it isn't the drum unit by turning the machine off open the top cover remove the toner and underneath you will have the dev unit unplug and lift out then remove the transfer tray (the one you open if there is a jam) open side door remove waste tank then you have the drum unit now to remove there is either a push button or a screw do either one that corresponds and check the unit. If there is a black line on one side the only way to get rid of the line is to replace the cleaning blade as this has worn. you can clean the drum unit cleaning blade it may only be toner stuck under the blade all you have to do is rotate the drum the opposite way of operation and if you have to hand a air line just give it a blast failing this it will defently need replacing.
Hi,i will do this: Remove toner,then remove developer unit.Try to clean magnet roller on developer unit with dry cloth, if see lines on roller.Pull out paper transport unit(green handle ) and clean transfer roler and vacuum it.Then ,when is paper transport and developer unit out, remove drum unit(open door on the left side on the printer and pull out drum). Remove Corona from drum unit.Remove and clean grid,corona inside and corona vire.
Check fuser and drum for scratches.
