Question about HP LaserJet CM1017 MFP All-In-One Color Printer
1)Magenta and Yellow doesn't print 'full blown' color. The color 'Red' came out 'Pink' rather. 2)They also mis-align - like creating a shadow. I can see a layer of red next to a layer of yellow, and they suppose to be overlap.
3)Color on both edges (left and right) seem to fade out.
Already did Cleaning, Calibrating, change of toners, air dust all interiors, update software & driver, etc..
You've 2 0r 3 problems here.
First NEVER use an air blower in a laser printer. You'll just blow toner deeper into the printer and could make things worse AND there's potential for damage due to static from the air blast. I've seen priners that were working OK, but had a leaking cartridge in them - 'cleaned' using an airline, and they never worked again !!
Problem 1 - weak magenta and yellow.
This will have started with the magenta being weak, become weaker, and later the yellow will have also started to deteriorate.
Dirty laser unit - needs (careful) cleaning internally.
See ' Printing Weak Magenta', 'Printing Light Magenta' for HP CM1015, HP Color Laserjet 1600, 2600, 2605.
All the same laser unit.
Problem 2 - Misalignment (Out of register) colours.
Registration of the colour cartridges, so that they can be used together to produce the colours in between the yellow, magenta and cyan of the cartridges themselves, takes place during 'calibration'.
If one of the sensors on the Transfer belt fails, the calibration seems to take for ever (and actually fails), giving rise to this colour offsett. The sensor is not available, and not replaceable, you'd have to change the Transfer Belt.
Your symptom 3 is related to the problem 1 above.

You can run a test print to confirm outage, and then later the fix,
by pressing a small button inside a screw closed cover plate on the back of the Printer. Printout consists of a series of colored lines.
The following is pretty intensive. You may want to provide these
instructions to a techician so he will have some idea what to expect before he gives you a quote.
To access, remove and clean Laser Unit.
1. Remove both side panels; left panel has screw at bottom in
cavity. The right side has screw near bottom rear below
RJ45 jack. Do NOT pry apart at top, open the front of the
printer and pry the sides apart along front and bottom pull
out several inches and then slide downward to disengage top.
The front of the printer can be closed and the toner
cartridges even remain installed for the rest of this
2. Remove back panel by removing 10 screws and swing panel
upward (hinged at top); disengage.
3. Disconnect connectors on both circuit boards (6 on left
board/15 of 16 on the right board) leave the 3 pin in
lower left corner of right circuit attached. Move all the
cables well out of the way; this requires the 3 black
plastic channels that hold the wires to be removed as well.
4. The two smaller channels have fingers that must be flexed
to allow extraction. The 3 ribbon cables exiting at upper
left corner need to be folded back and the metal "bridge"
flexed (almost bent) up to disengage tab and allow black
channel to be removed that's under it. Slide the long
channel left to disengage.
5. Remove 5 screws and then remove left circuit board.
6. Now remove the next panel by removing the dozen or so
screws around the perimeter. Two, in upper left and lower
left corners are screwed in from the side. Lift up bottom
a few inches and slide down to disengaging tabs at top.
The rather larger black rectangular Laser unit is now visible.
7. Remove the 4 screws and the Laser Unit. Disconnect the
2 ribbon cables and lift unit out.
8. Set unit on its back. Remove the small spring. Remove the
single screw from middle of cover, and then remove cover.
9. Short lesson: The 2 circuit boards on side have 2 each laser
which aim towards the middle of their respective chambers.
There is a square reflective device on a motor shaft called
a scanning mixer which when it spins directs the laser beam
to two respective prisms and then into the respective toner
cartridges. There is also a pair of Beam Alignment Lens
along each path.
10. OK, the top of the unit has the wire cable, if you examine
the prisms, the two lower ones in each respective chamber
will have a thin layer of toner coating them. Also the two
cupped looking clear plastic Beam Lens between mixer and
prisms could also have layer of toner. Anyway, clean the
Prisms, and both Beam Lens with Isopropyl rubbing Alcohol
and Q-tips swaps. Be careful, you do not want to dislodge
11. When I cleaned my CM1017 Laser unit, I was surprised at how little toner residue had the negative effect. Apparently it
doesn't take much residue to render the laser ineffective.
This explains the advice not to attempt blowing things out
with a can of compressed air. Although with the laser unit
dissembled and removed from the printer, you may want to blow
it out after cleaning to remove any microscopic debris left
12. OK, when all is spotlessly cleaned, you can install the cover,
if you had removed the plastic shutter rod to enable cleaning;
make sure it is put back in unit. Screw on the lid. Reattach
spring. Test operation of shutter.
13. Reinstall the Laser Unit, attaching two ribbon cables and
making sure shutter arm engages correctly.
14. Reassemble in reverse order, steps 6 thru 1.
15. Run test print via the button on back of printer (under
screwed cover plate)
Oh, when I first turn on the printer, the display panel would not come on. I turned off and back on the and the display came on.
I hope this makes your day!
