The printer prints just fine. However, when the paper moves fast, such as when ejecting after printing, there is a disturbing screech noise. Sounds like a bearing somewhere, but it is difficult to localize. Most likely the last rollers in the path, near the front of the printer.
Is there an on-line manual identifying bearing points?

<p>Unexpected noise (such as clicking, thumping, or grinding) from an branded device are heard during printer operation.<br />
<span><b>NOTE: </b></span><br />
Noises can be caused by a number of things, some of which may not be addressed in this document. This document deals strictly with the isolation and potential resolution of known noises through troubleshooting.<br />
<p>The following table describes some of the noises to be expected in a printer functioning normally:<br />
<span>Noise occurs:</span> <br />
<span>Additional information:</span> <br />
During power-up<br />
When the printer periodically makes humming and buzzing sounds as the carriage assembly moves around on the right/left side of the printer, the printer is actually cleaning the ink cartridges. This is a normal operation for the printer. This sequence may happen in the following conditions:<br /><br /><br />
<p>Before and/or after printing<br />
<p>During power on <br />
<p>After the printer has been on standby/idle for some time<br />
<p>After replacing a cartridge<br />
<p>In the middle of a long print job (such as printing many photos)<br /></li></ul>
During printing*<br />
<p>Paper pickup: There will be some noise during paper pickup due to the movement of rollers and gears.<br />
<p>While printing: The unit has printed a few lines or the paper has been fed into the printing area. There will be some noise during printing due to the movement of rollers, gears, carriage and paper (paper feed and ejection).<br /></li></ul>
During paper ejection*<br />
At the end of the print job, there is a louder clicking noise as the paper is being "pushed off" to the output tray.<br />
During copying/scanning<br />
The scanner may make pulsing and dragging noises as it scans portions of the document or it may make a long rolling sound if it is doing a continuous scan. After scanning, it will make a long dragging noise as the scanner is brought back to the home position (could be on the left or right side).<br />
Post-printing with no additional jobs in the queue<br />
Post-completion of a print job and without another job in queue: At the end of a print job, there will be a noise on the left/right side of the printer as the pens are being capped. The printer may try to do this a couple of times, which is normal.<br />
Between print jobs<br />
The printer may make humming and buzzing sounds as the carriage assembly moves around on the right/ left side of the printer during the cleaning of the ink cartridges.<br />
In the accessories<br />
There may be some noise associated with accessories (ADF, duplexer, etc.) during the initial positioning and during normal operation.<br />
At the end of the printing cycle, when the paper ejects from the printer, it is heated to fix the toner onto the paper. The heating unit is covered with a Teflon film sleeve, which rotates as the paper moves over it. The crunching noise could be due to the broken damaged teflon sleeve, which requires replacement by a professional.
Yup. I suspect the head has been removed from the unit. There are adjustments on some printers. It was assembled wrong. The grating noise is likely the auto cleaner. If it cannot go 'home' the unit will not initialize. Possibly the head detect sensor is broken or covered. If the head will not home (moves out and back more than once or slams home hard), 'Init Unable AF'. You may be able to order a service manual from Brother for this. A repair shop can order the manual as well. (I suspect you need a new print head as well. You might want to replace the printer) see tips on bubblejet printers.
Make sure you inserting the paper not deep inside just insert and stop it when you feel any resistance .and try to print something. If it is print then well otherwise you have to show it service center.
i believed this issue is on the mechanical side of the printer.if the grinding noise is very noisy if you still have the warranty of the printer you can go ahead an ask for the replacement of the printer coz it is an issue with the mechanical part of the printer..
If you haven't already done so, look into the printer roller areas, and look for a piece of paper stuck somewhere, or maybe a paperclip or other foreign object which has found it's way into the mechanicals. Also, check the printhead assembly for free movement.
