Question about HP OfficeJet 7310 All-In-One InkJet Printer
HP Officejet 7310xi All-in-One Printer: I was having alignment issueswith my printer after changing the ink cartridges. I followed the stepsHP provided and now my printer keeps giving me a ''Carriage Jam'' error.There is nothing blocking the carriage from moving and I am able tomove it manually without any resistance. I have already been on chat support with HP with no luck. They had me try all of the things I had tried on my own. Any suggestions out there?

I have an Hp Officejet 5110. I have an error message saying "Open door,clear carriage jam, then press enter". But where is its door? How can I clear the carriage jam?
I tried pressing the # & 6 at the same time, but the error message still there.

SOURCE: 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

Hi Guys, Had the same problem, tried the idea from Kate712 with some joy but not for long (now Ive got ink all over me). Played around with the encoded position tape that runs the entire length of the left/right travel. Mine had a slight twist to the right side. Maybe the twist was preventing contact with sensors the brains use to establish carriage position, Im not 100%. Tried deliberately twisting the tape to re-create the fault and got the same error message to re-appear. Theres like a garbage bag tie arrangement in this position tape thats used to secure it at the right side of the carriage. There is an arrow type push through arrangement that feeds back around a support and through itself with an arrow. Mine only had one point of the arrow though the hole and once I pushed the other through the tape untwisted with a little poke with a pen. Hope this helps

the silver bar the carrige slides on has lost all its lubrication. Try putting some chapstick on the silver bar
