Can't get cover off Canon S630 printer

The cover of this dratted Canon S630 printer has slots with little triangles by them instead of screws. How do I get it off?

The reason I need to open it is because I have the dreaded "home head" error (print head stuck on rail toward right hand side), which I'm almost sure is accumulated cat fur. I'm hoping I can clean it out.

    This doesn't take a special tool. The triangles are labels stamped BELOW (and pointing to) the slots. It's one of those deals where you use a flathead screwdriver to push a tab or something inside the slot. Then you have to do something else with your other hand (which I can never finesse; I'm always afraid of breaking some tiny piece of plastic). Or maybe instead, all the slots have to be poked simultaneously.

    With some on-the-scene help, we finally figured it out. There is a slot on each side, and two slots on the back (four total). The slots on the back are low on the curved pieces that flank the sheet feeder.

    Inside each slot is a tab. By inserting a small flathead screwdriver (or a key) into both rear slots simultaneously, the tabs that hold the back of the cover on can be freed. The same thing needs to be done with the side slots, and the cover can be rolled forward just a little bit then lifted straight up.

    The reason for the lift: underneath, there are also two places at the front where pieces of molded plastic inside the cover sort of plug into corresponding pieces on the base. Fortunately, no tabs have to be released at those points.

    Getting the cover back on is also a bit tedious. There's absolutely no clearance, and everything has to be positioned precisely before you start pressing down. I was able to succeed only when I did the process in reverse, fitting the two front "plugs" together, then clicking down the two side tabs, and finally the two rear tabs. Perhaps there's a better method, but I couldn't discover it.

    If one of the tabs catches while the cover is askew, the screwdriver trick must be used to release it before you can start over.

    Unfortunately, I have not been able to resolve the printer's problem. I did clear out a LOT of fur, but now I have a new problem ... which I will describe separately.

Paper jams as a result of string feeding in through the paper fee

Both side covers come off first, then you unplug the scanner and remove. Canon uses a combination of screws and plastic clips to hold covers. You use a screwdriver and insert wherever you see a little triangle pointing to a hole. mark the plugs so they get back to the right place, good luck!!

The timing strip drop off

you need to remove the covers and get to the carriage area and put back on the strip it just slots in on one end and usually a little spring and a metal piece holds in on the other end.
you would be getting error codes as it is as the print head doesnt know what position it is in

"Paper Output Slot Jammed" Canon Pixma iP4300

These printers are FULL of very sensitive sensors, and chances are that one of them may have a small piece of paper blocking them. If you can get the covers off by finding the "Triangle" arrow markers, you can inspect all these sensors.

Good luck!!!

Canon ip3300 printer

I fixed mine just last night, with the same symptom.

This is not an easy fix, but it is FREE!!!

On the bottom of the printer, on the inside of the case, there is an optical sensor that reads the positions of the roller going to the feed tray. I found ink had blocked that sensor, and was causing the error.

Getting to that sensor is not for a novice. Getting into the case is the most technical part.
Find the "arrow" points. These are points on the printer that indicate the release points for the outer shell. There are triangle "arrows" pointed at small, or large "slots" that if a small flat blade screwdriver is inserted, will release the covers.
Find the first under the carriage cover, at the left and right sides. A 1/4" by 3/8" cutout in the top of the black horizontal surface, about 4" from the center to the left and right, and about 2" back from the front. Insert a flat screwdriver, and rotate the screwdriver handle toward the center of the printer to release A PORTION of the left and right side covers. Note the triangle arrows. Now find the others!!!
Happy hunting! If you get the covers off, write back, and I'll tell you how to find the clogged sensor.

How to dismantle the canon i560 cover

To open the case, there are 6 slots holding the top cover in place. Insert a flat blade screw driver into the 2 slots at the rear while (gently) pulling the rear end of the cover up. Do the same thing for the 2 side slots, again (gently) pulling(prying) up the cover. Then, remove the 2 side (decorative) covers by (gently) rotating the rear portion down of each downward. They are held in slots by 2 plastic hooks and in front (the wrap-around part) by a tab. Once they're removed, the 2 remaining slots can be reached. Use the screw driver to pop up the front part of the cover. Then the interior of the printer is exposed.

Good luck!

Error message on canon i900D

1. Underneath the printer, look for the triangular arrow on the AC Adapter, which points to a detent. Fully depress the detent, remove the AC Adapter and unplug it. Align the cable so that it will pass through the hole in the case when you remove the printer assembly.
2. Open the front cover to the vertical position and tug it at the hinge points to remove it.
3. The black, card-slot cover has two holes marked by triangles. Remove the two Phillips head screws, being careful not to lose them in the printer mechanism. Coax up card slot cover with a dull knife or similar tool and remove it.
4. On the top left of the printer, notice the triangle point at a slot. Insert a screwdriver or similar tool into the slot and depress the detent. Ease the little cover over the USB cable connector towards the rear of the printer and remove it.
5. Remove the “Operation Panel and Window Display” (OPWD). Lift the window display to the horizontal position and remove the two Phillips head screws. Rotate the OPWD forward and out the two hinges at the bottom. Lower the tiny snap that holds the OPWD strap cable and remove the OPWD.
6. Note the slot marked with a triangle between the two OPWD hinge slots. This is one of the six slots, all marked with a triangle, which access the detents that hold the upper casing. Locate the other five. One is on the left-side front of the printer in the same relative position as the one hidden under the OPWD. The other four are in the rear of the printer. Depress these detents in turn, working around the printer, and coax up the upper casing. This requires fortitude, patience and one or more dull, thin instruments.
7. On the right side of the printer, remove the Phillips head screw that fastens the yellow wire to the chassis of the printer.
8. Disconnect the connector on the Digital Camera Connector (DCC) circuit board and ease the cable out of the printer casing as far as you can. (I feared damaging the connector and removed the circuit board and DCC cover instead.) This cable is hooked at the right hand rear corner of the printer casing.
9. Looking down on the printer mechanism, locate the two Philips head screws near the rear. These fasten the printer to the base. Remove them carefully.
10. Placing a hand under the paper feed barrel, lift the printer assembly up and rest it on the case while you fight the DCC cable off the hook at the right rear corner. Once you free it, remove the printer assembly and congratulate yourself.
11. Wearing disposable gloves, remove the five ink absorbent pads and rinse them under the facet in the laundry sink. Cold water is fine. Press the pads with your fingers until the water runs clear. Do not wring or otherwise torment the pads, as you want them to retain their shape. Press the pads between old newspapers to squeeze out most of the moisture. Expect to be surprised at the amount of liquid these felt pads can hold. I dried mine in the sun. Use a hair dryer, clothes dryer, microwave or oven at your own risk.
12. Reassemble the printer in the reverse order of disassembly.
12.1. Insert the small absorbent pads first. The right side pad with the green facing goes on top. (I think.)
12.2. Caution: Before replacing the upper casing, note the small electrical gismo on the left side of the printer assembly. It has a slot that fits into the plastic wheel. When properly positioned, the gismo snaps into place. Make sure the gismo is correctly seated before replacing the upper casing.
