The bent pins are fine because that the way they were created. Print head cleaning is critical in printer. You should know the risk of cleaning it. It might have been scratched hard. Please double check the printhead for any possible loose connection.

Canon mg 3550 alignment problem?


Dear sir

I have encountered this problem on other printers. Try to clean the ribbon sensor found just above the head. It is a plastic digitizer strip used to align the head movement. Usually it has some grease on it just clean it with some cloth very gently.

My printer only prints a 5/8" wide strip across and skips about the same horizontal width. In other words for some reason it looks like a zebra!

I have a Canon Pixma MP270 and I can only print in colour both the black and colour lights are lit up on the printer


f print quality does not improve by the standard cleaning of the Print Head, clean the Print Head deeply. Cleaning the Print Head deeply consumes more ink than the standard cleaning of the Print Head, so clean the Print Head deeply only when necessary.
1. Make sure that the power is turned on.

2. Clean the Print Head deeply. (1) Press the g0022565.png (Maintenance) button repeatedly until y appears. g0054776.png
(2) Press the Black or Color button.
The machine starts cleaning the Print Head deeply. Do not perform any other operations until the machine completes the deep cleaning of the Print Head. This takes about 2 minutes.

3. Check the print head condition.

When the deep cleaning is completed, the LED returns to the copy standby mode. To check the print head condition, print the nozzle check pattern.

See " Printing the Nozzle Check Pattern".

If the problem is not resolved, turn off the power and clean the Print Head deeply again after 24 hours.
If the problem is still not resolved, replace the FINE Cartridge with a new one.

See " Replacing FINE Cartridges".
If the problem is still not resolved after replacing the FINE Cartridge, contact the service center.

Printing the Nozzle Check Pattern
Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzles.

NOTE If the remaining ink level is low, the nozzle check pattern will not be printed correctly. Replace the FINE Cartridge whose ink is low.
See " Replacing FINE Cartridges".



You need to prepare: a sheet of A4 or Letter-sized plain paper

1. Make sure that the power is turned on.

2. Load a sheet of A4 or Letter-sized plain paper in the Rear Tray.

3. Open the Paper Output Tray gently, and open the Output Tray Extension.

4. Print the nozzle check pattern.

(1) Press the g0020617.png (Maintenance) button repeatedly until A appears. g0054754.png
(2) Press the Black or Color button.

The nozzle check pattern will be printed.

5. Examine the nozzle check pattern.
See Examining the Nozzle Check Pattern.

Examining the Nozzle Check Pattern

Examine the nozzle check pattern, and clean the Print Head if necessary.

1. Check if there are missing lines in the pattern (1) or horizontal white streaks in the pattern (2). g0054755.png (1) Check if lines are missing in this pattern. If yes, the cleaning is required.
See " Cleaning the Print Head".

g0020623.png
(A) Good
(B) Bad (lines are missing)

(2) Check if horizontal white streaks are present in this pattern. If yes, the cleaning is required.
See " Cleaning the Print Head".
g0020621.png
(A) Good
(B) Bad (horizontal white streaks are present)

Printing lines not straight and letters shadowed. Help!


Open the cover over the print head and *carefully* inspect the clear thin plastic strip that runs from left to right near the print head. If you see any lubricant (white grease) on this encoder strip, it needs to be cleaned off.
1. With the cover open and the print head in the center, unplug the power cord. This will allow you to gently move the print head left or right.
2. With a cotton swab wetted with rubbing alcohol, *gently* wipe the grease spots from the encoder strip. (Be VERY CAREFUL you don't dislodge the strip.) You may need to move the print head to the left or right to get all areas cleaned.
3. Let the alcohol dry off completely. With the area clear of cleaning tools, debris, and fingers, plug the power back in.
4. Try a test print.

Print head


I encounter exact same problem. What I did was took out the print head and clean the print head with Qtips with alcohol. To locate and remove print head, follow the instruction at Canon's PIXMA MP830 website and choose the tab "Support & Service" type "rseating the Print Head"
You'll be seeing
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=123&modelid=12804#SupportDetailAct

Basically, printer head is inner carton where ink cartridges sit.
Above link shows pricicely how to remove the ink cartridge.

Above link's instruction says, Caution: do not touch print head nozzles<1>

But, I just went ahead and clean the print head nozzles with rubbing alcohol soaked Qtips.
After completely cleaned and dried, I reinstalled print head, reinstalled ink cartridges,
closed all the cover. It went back working perfectly.
