DP540CJ. How can I reassemble the paper feed lever?

give one paper per feed and try.

it must detect the paper.

if the paper is getting pulled in one side it must be OK with sensor.

just a proper cleaning work may be required

Although paper jams occur because of dirty pickup rollers I have found that jams occur frequently because of solenoids in the paper feed mechanism (the assembly that the paper trays fit into). There are two of them and over time the damping foam on the levers get sticky causing the lever to operate late which causes the jam. As a fix I remove the damping foam and put insulation tape on the lever making sure the solenoid works by using a 12v bench psu before reassembling. You will need service manual because Paper Feed mechanism removal is a little complex.

Paper feed problems in Canon Laser Jet Printers are caused by these solenoids mainly in Duplex mode. P3005dn's etc.
Hope this helps solve yr problem.

Paper Loading

Rear Feed, Continuous Forms

Use the rear-feed path for printing on single-thickness,

continuous-form paper.

Use the single-sheet path (top feed) for graphics or charts.

! If you have paper in the paper path, be sure to remove it

before installing rear-feed paper.

1 Lock Lever

2 Upper Tractor Cover

3 Pins

4 Lower Tractor Cover

1 Move the paper lever to the position marked "REAR."

2 Grasp the tabs lift off the paper separator.

3 Pull up on the lock levers and open the tractor covers.

Then, move the right tractor to fit the width of the paper.

4 Place the first two holes in the paper over the tractor pins

on either side. Close the tractor covers.

5 Move the left tractor to align the edge of the paper with

the appropriate reference mark (1). Then, push back the

lock lever.

6 Adjust the position of the right tractor to center the holes

in the paper on the pins. Then, push back the right lock

lever.

7 Install the paper separator. Place the wire guide (1) on the

pull-up roller assembly (2).

8 Press FF/LOAD. The paper feeds into the printer.

! The factory default setting for the Top of Form (where

the printing should begin) is one inch down from the top

of the page. To change the setting, see "Using Your
Printer, Top of Form (TOF)."

Top Feed (Single Sheets)

Use the single-sheet path for letterhead stationery, memos,

and individual envelopes.

! If you have continuous-form paper in the path, press

PARK to remove it before loading single sheets.

1 Make sure the printer is on and deselected (SEL light off).

2 Place the paper lever in the position marked "TOP."

3 Open the carriage cover. Raise the paper separator to the
single-sheet position.

4 Make sure the wire feed guide (1) is secured in the sheet

guide.

5 Adjust the paper feed guides (1) for the width of the paper.

Place a sheet of paper in the separator. The paper will feed

into the printer.

Brother paper jam error message is displayed by the printer when paper is jammed in one or more locations. In such a case, users are recommended to remove the jammed paper from the specified location. The entire paper path must be checked for any pieces of paper.

• To stop the message, open and close the top most cover of the printer.
• Lastly, verify the flags and the sensors.
• If the problem persists, the cause of the error message could be a broken sensor or sensor lever.

If I recall the KXP series, it is a track feed printer as well as sheet feed, there should be a lever on the top that you can move to different positions, one position is for feeding paper without the rollers, when the lever is placed in a different position it releases the rollers so the printer can feed the paper. The open position is for installing paper or clearing paper jams. Also if I recall, the lever is on the right side near the roller on the end. When you move the lever, and turn the roller, you fill feel it grab the paper. There is also a switch on the front for line feed and page feed allowing you to tear off a page and then pressing it again will reverse the paper to print position.

If you have it set to certain paper weights or manual feed that is all you will get. Change the settings from the printer monitor back to normal weight paper or text not high quality graphics and it should feed again.

This could be caused by several parts, the most likely is the paper eject sensor lever & spring being out of position. Get a stiff piece of A4 card such as the backing from a note pad. Make sure the print head is in the parked position (fully right). Position card in the feed hopper and push through the feed mech. Open the top and watch for the card to come through the printer. This should realign the lever and also clear any obstructions in the paper path. Always try to remove paper jams in the direction of the paper feed, pulling backwards can damage levers etc.

Please take a moment to rate this solution. Thanks.

You aren't fusing (melting) the toner to the paper. The probable cause for this is having the "envelope feed" levers in the "envelope", or up, position. This leaves a wider path for the paper, which does not allow the toner to be fused onto the paper properly.
The envelope feed levers are the two small green levers at the rear of the printer, one on each side, that are visible when the printer's top is lifted.

I had exactly the same problem. It is caused by the paper feed rollers becoming shiny and failing to get a grip on the paper. The cure is easy. Disconnect the cables, remove the paper tray and turn the printer upside down. Carefully peel off the two rubber 'tyres' on the ends of the feed roller, turn them inside out, and refit them. Reassemble the printer and it should work perfectly. Obviously, you can only do this once......!
