Hi
Going to resurrect this old thread as my experience may be of some use.
My HP 7520 kept coming up with error 0x610000f6.
You could hear the carriage moving and clunking as it hit the end stops.
Thought it was probably the encoder strip or sensor took the printer apart and cleaned / checked both looked ok. reassembled the printer still no joy.
As I had the sides off the printer I noticed that the ink catch / cleaning tray seemed to not want to move (mentioned in post above).

with the side off the printer it is easy to move the tray. After a bit of wiggling the printer booted up ok.
It still errors every now and then but again a bit of fiddling sorts it out until next time.
I should strip it down and find the problem but as the whole ink trak is filthy I cant be bothered.
Maybe if it gets worse I will if I do I will post some pictures.

Here is what you need to do to check the ink tray:

Open the lid as if you were going to change cartridges. Does the carnage move freely? If not then you probably have a different problem.

On the right hand side (opposite the screen) there are two torx screws you can now see under where the lid was.

Remove these.

Remove the ridged plastic band that runs around the bottom right hand side of the printer.Start at the front lever the top left hand corner out with a small screwdriver. Whilst holding this out slide the front section to the right. Once this has unclipped pull the whole ribbed piece of plastic forward. Now the ribbed plastic band should come away.

Remove the side panel that the two screws held in place.

Now you can see into the printer.

Close lid and turn on and look and see what happens. If the carriage moves from side to side and hits the end stop on the open side of the printer but the small white gear under the ink tray does not move then it is jammed as mine was.

Turn off printer. Open lid again. move carriage out of way.
Put some disposable gloves on. Where the carriage stops on the right had side it pushes a small lever. Push this with one hand with the other hand gently move the ink catch tray back and forth.

Once it is moving ok pus back to back position.

Close lid power on. Hopefully that will sort it out?

Spent ages looking on the internet for a solution this thread was the closest I found, amongst all the HP junk telling me I had a paper jam. Hope this is of use to someone.

SOURCE: error - carriage jam message

My Photosmart 2610 just started having this same problem today. As many of you have done, I also went to the hp support website and tried just about everything. Finally I discovered the answer to my problem on my own. Here's what I did (you might want to have a wet rag handy to wipe the ink off your fingers):

1) With the printer on, I pressed "okay" to clear the error message. You should immediately hear the sound of the carriage (the contraption that holds the cartridges) moving inside.

2) Open the print cartridge access door (the main access point for the cartridges) and confirm that the carriage is indeed moving.
If the carriage won't move at all, I'm not sure that this solution will help you. However, if the carriage moves from side to side after you press "okay", please read on.

3) This is unorthodox, so bear with me: when the carriage moves away from it's "resting place" (in my printer it's on the right hand side) and is near the center of the printer, unplug the power cord from the printer. The purpose of this is to free up the undercarriage (which was the part that actually was jammed on my printer).

4) Ensure that the carriage moves freely from left to right and right to left by pushing gently on its sides.

5) Move the carriage to left side of the printer so you have room to access the undercarriage.

6) It might be helpful to have a flashlight or some other light targeting the undercarriage for this next part. If you look directly underneath the undercarriage, you should see a foam/spongy product resting in the base of the printer. The purpose of the sponge is to absorb any ink that escapes from the cartridges. Herein lies the problem: over time, as the undercarriage adjusts to enable the carriage and its cartridges to do their work, the undercarriage gets caught on the inky sponge. Note that the undercarriage is fragile, but is moveable by gently pushing it toward the front or back of the printer.

7) Adjust the undercarriage so you can see the sponge and the "axel" (for lack of a better term) that turns to move the undercarriage forward and back. It may take some detective work, but you should be able to determine where the sponge is supposed to lie. Your goal here is to push the sponge down as far as it will go so that it won't obstruct the movements of the undercarriage.

8) On my printer, there was also a small amount of sponge wrapped around the "axel" that prevented it from moving smoothly. I unwrapped it and double-checked that nothing else was obstructing movement.

9) Final step: leave everything where you moved it, shut the lid, and plug it back in. A little prayer never hurts either. Good luck! AIM ID if you need more help: GnarlyVeaux

SOURCE: carriage jam issues on hp printer

So sorry to hear that you are having issues with your C4385 printer. HP's All-In-One printers seem to be very touchy when it comes to carriage jams, and mine is no exception. They are usually caused by little bits of paper left over from a previous jam, so you just have to work out where to find them. HP produced a page with diagrams to help people find them. Please click here to access their solution page.

Hope this helps!

SOURCE: carriage jam

Sorry about the B.S., you can move the carriage by hand, and all you need is to clean the encoder strip that runs across behind the carriage assembly. You can wipe the strip gently with an alcohol swab or a Q-tip moist with alcohol. The bars on that strip tell the carriage where it is and grease or ink on it will give the carriage jam error. No calibration necessary after moving the head or cleaning the strip.

HP Photosmart C4100 All-in-One Printer we keep getting the carriage jam message

Carriage jam errors refer to the "carriage" that the ink cartridges sit in. The errors can be caused by a lot of things including lack of lubrication of the belt, something being inside the printer, etc. Check to see how freely the carriage moves back and forth when the printer door is open.

What do you need help with? Hp Deskjet 2645 is showing error code and it refusrs to print

The carriage that goes back and forth when printing may not be moving freely. Turn off all power and see if you can move it back and forth easily. If not, put a drop of light oil on either side of the cartridge holder and slide it back and forth. You can also clean off the carriage rod with a cloth before oiling.
If this does not clear up the error code, the main board has failed and it will not be worth repairing, unless the unit is under warranty.

HP Photosmart Premium C309 with all lights flashing. Won't do anything, even scan. No resets work. All I want to do is scan. Help.

Either the carriage is jammed or there is a major electronic board failure. With the power disconnected, try to move the carriage back and forth with your hand. If it seems sticky, clean off the carriage rod and put a drop of light oil on it. Then work the carriage back and forth until it moves freely. Plug in and all should be well.
If this does not help and you can't find any jammed paper or objects, you have a major failure and it will be cheapest to buy a new unit.

Why does my HP C4480 say "carridge jam" and flash when there is no paper inside the machine and I've cleared the carriage to the left? I have to turn it off and back on to have it work again.

Paper has nothing to do with the carriage jam. Something is hindering free movement of the carriage back and forth. Check to see that the carriage moves freely, and there are now buildups of dirt or trash in the area. You may wish to reset the print cartridges to ensure they do not hang when moving.

HP Pro 8500 printer has carriage jam. I have opened every door and there is no paper jam.

Sometimes the paper gets caught inside the printer all the way to the right (or left) of the print carriage. You will miss seeing it because the print carriage has moved the jamed paper to the right (or left) out of view. Carefully and manually move the print carriage to the opposite side and you might find small pieces of jammed paper there.

HP Officejet 7310 carriage jam

I'll start by explaining some of the components you need to understand to troubleshoot the carriage system.

The Carriage is the thing the cartridges are mounted in, it slides on the carriage rail, the bushings in most newer carriages are made of plastic, (or maybe it would actually be called a polymer, or composite material). The bushings are the pieces that wrap around the carriage rail.

The carriage rail is a shiny round rod that the carriage rides on, it is driven across the rod by the carriage belt, by the carriage motor, at the opposite end of the belt there is an idler pulley, ".

In a HP printer the device where the carriage parks, (sits at), when the machine is not printing is called the service station, it is responsible for cleaning the print heads, and for capping the heads when you are not printing, (so they won't dry up). The bottom of the service station is the "Spittoon Base", ink is spayed into the base before printing to prime the heads, there is an absorbent pad in the base to soak up the ink. Note that the pad does not always soak up all the ink, so if you tilt an HP printer you can spill the ink out of the service station, (especially if it is a heavily used printer). The piece that moves back and forth in the service station is the "Sled", it was wipers to clean the heads on it, and the caps that keep the heads from drying out are also part of this assembly. The sled is moved back and forth before the carriage leaves the service statio to wipe the heads, this happens after the heads are primed, then the carriage is moved off the service station and the sled is again moved back and forth to clean the wipers.

The encoder strip is a plastic timing fence that looks clear at first glance, but has black lines painted on it. The strip is threaded through an optical sensor on the back of the carriage.

When the printer initializes the carriage has to leave the service station, or, if the machine was powered off when the carriage was somewhere else, whatever spot it is sitting in, and travel the way to the other side of the printer, and then return to it's home position which is the service station.

When the carriage reaches the side of the printer away from the service station it sets that as a reference, then it counts lines on the encoder strip as it travels home, if it doesn't see enough lines before it gets all the way to the other side and can't move any more then the printer decides the carriage must have something blocking it.

Sometimes a service station will fail in a way where the sled does not retract fully, if that failure happens when the carriage is parked then the carriage will usually not be able to leave the service station. If the service station binds when the carriage is off of the station, then the station may not be able to move all the way to that side, and will detect a carriage jam. When the service station binds you might hear a grinding noise as it's motor tries to drive the sled back and forth.

If the encoder strip is dirty the printer may not see all the lines and detect an error, often when the strip is dirty the carriage will move too fast and slam to one side of the printer.

I use water to clean the encoder strips in HP printers, water works well on water based inks, if your printer uses ink with another base you might use alcohol, but "ONLY" if the ink is not water based.

One end of the encoder strip is attached to a spring mount, if you wipe the strip starting at the end that is attached to the frame, and wipe only towards the spring mount, then the strip will stay attached to the printer.

A dry carriage rail will cause the carriage to bind, if the carriage does not move fast enough a carriage jam will be detected. Some newer HP printers use grease on the carriage rail, many models use a liquid lubricant, Use "ONLY" light synthetic or silicone based lubricants on printers that use a liquid lubricant, Petroleoum based products may melt the plastic bushings and ruin the carriage. (YES, Petroleoum based means WD-40)

some HP printers have a timing disc on the service station, and if the service station binds, or the timing sensor fails they report a carriage jam, but as far as I've seen that jam always occurs before the carriage moves.
You can use a synthetic lubricant on the carriage rail :hope this helps

Carriage is jam, black is in the wrong place

I have had frequent "carriage jam" messages from my HP 2355. I would open the lid, move the carriage back and forth many times, unplug it and then restart it, and eventually it would start printing again. Today, however, this did not work.

I resolved to either fix it, break it or throw the printer away. Lucky for me, I finally found the root cause of my problem.

Under the spot where the cartridges "park", there is a platfrom that has a few wipers on it. Mine was covered with old, dried ink. I discovered that this platform is supposed to move, front to back.

Mine would barely move. So, after pushing the carriage out of the way to the left, I pushed this platform toward the rear of the machine and then sprayed the area judiciously with Simple Green. Then, I used an old toothbush and paper towel to clean the sliding surface and generally removed crud from it. Latex gloves are highly recommended!

After this, I moved the platform back and forth and continued cleaning until it moved smoothly and easily. It solved the problem and the printer does not need to take up landfill space!
