A paper feed issue can occur for several reasons, such as dusty or contaminated paper rollers, the condition of the paper in the tray, or even issues with the software.
The printer`s laser projects your print onto a drum. A drum then uses static electricity to attract the dry toner to the drum`s cylinder. The drum then rolls the toner onto the paper to create your print. The toner powder is melted and pressed onto the paper with heat from the fuser as it goes through a set of rollers.
Check Cables and Printer USB Ports

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

Slide the paper all the way into the printer. The leading edge of the paper will stop at the Paper Drive Roller. Locate the Paper Sensor/OOPs sensor on the right side of the paper path. It can be seen from the top of the printer with the Top Cover open and has red, black, and blue wires attached to it.
Over time, paper absorbs and loses moisture which causes it to warp, or not lie perfectly flat. This can create print quality issues like jamming and is something to consider when using a printer that hasn`t been used for a while.
The printer`s rollers are the ones responsible for pulling in the sheets in the input tray.
The printer heat a small quantity of ink by passing an electrical charge through a resistor. The temperature of ink reaches 900oF in a short time interval. The heating element vaporizes a tiny layer of ink for a few millionths of a second to create a bubble. Some of the ink is then pushed out of the nozzle.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
Capacitive sensors can detect objects that have a dielectric constant that is different from air. Hence, these sensors can detect objects made from a wide variety of materials such as plastic, paper, wood, etc.
The automatic paper type sensor functions when a tray is configured to the. Any Type. or plain type. setting. After it has picked up paper from the tray, the product can detect overhead transparencies, paper.
Capacitive proximity sensors can be used to detect and count non-metallic objects such as glass, paper, cardboard, plastic or wood. This is possible because the sensor can detect more than one type of material unlike the inductive proximity switch.
Sometimes a paper jam error persists even though there is no jammed paper (false paper jam). Reset the printer, which might clear a false paper jam error, and then try to print again. With the printer turned on, disconnect the power cord from the printer. Unplug the power cord from the power source.
The paper has holes along both sides that fit over the sprockets located on the feeder wheel. When the wheel turns, it feeds the paper into the printer. The holes are torn off the paper after the printout is complete. And, yes, printers still use this type of feeder mechanism.
Paper Feed Rollers

Created with a blending technology developed based on our extensive experience, these materials offer both a high friction coefficient retaining characteristic and superb abrasion resistance. We also mass-produce belt-shaped samples, in addition to ordinary rolls.

Thermal paper (sometimes referred to as an audit roll) is a special fine paper that is coated with a material formulated to change color when exposed to heat. It is used in thermal printers, particularly in inexpensive or lightweight devices such as adding machines, cash registers, and credit card terminals.
If the paper feed rollers are dirty or paper powder is attached to it, paper may not be fed properly. In this case, clean the paper feed rollers. Cleaning will wear out the paper feed rollers, so perform this only when necessary. Make sure that the power is turned on and remove any paper from the rear tray.

paper drive wont accept paper
ANSWER : There is probably a small scrap of paper stuck at the left edge of the paper path. The paper hits it and skews to the left. The smaller size bypasses it. You need to shove something stiff, like a piece of file folder, down the paper path and attempt to dislodge it.

Multiple paper feed
ANSWER : Most likely the pickup roller solenoid is sticking. The way it works is the solenoid energizes, pulling down a metal plate that releases the pickup roller. There is some foam on the base to quiet the clicking sound. The foam deteriorates and the plate sticks to the gooey residue. This allows the pickup roller to continue to turn instead of stopping after one revolution when the plate springs back up. That results in multiple paper being fed. Solution is to find the solenoid, which is at the end of the pickup roller shaft. Remove the sticky foam and preferably replace it with some thin sticky backed felt. You can find it at a hardware store as it is used on the bottom of chair legs.
