This has been a great work-horse printer, but at the moment is not much more than a 70 lb doorstop. I'd like to get this thing working again but nobody I can find locally repairs these printers. So I thought I'd try my hand at fixing it myself.
I'm getting a dark smear down the right side of every page. I've replaced the drum twice, and have replaced all toner cartridges. I've pulled out the cleaning rod and replaced the pad. I even vacuumed all the surfaces I could find to clean inside the printer and still no luck. Any idea what I can try next?
It Sounds like you may have damaged, or in some way stained the Fuser Roller.
The roller is situated on the top of the unit under the smaller opening flap towards the rear. release the blue levers and examine the surface of the orange roller, chances are the roller is marked.
New Fuser units are available from a number of UK sources but are pricey at around £100 (100k copies per unit).
The other possible cause is if you are using a refilled black toner cartridge. Dell toner units don;t like being refilled more than 3-4 Times and often leave a "ghost" mark on the page. try a new dell toner in the unit and see if ithat helps.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

weighing in the 140-170 lb. you should buy a punching bag weighingaround 70-90 lb. if your close to 140 you
should buy a 70 etc. if you a big guy weighing over 170 lb. you should get over
100 lb. bag. There is also heavy punching bags suitable for children and the
weight around 25-55 lb.
Based on the Media weight for a HP Deskjet 9300 The Main Tray can support up to 36 lb bond. The Manual Tray in the Back can support up to 70 lb bond via a single sheet. You must check the weight of the thick paper you are using to make sure your using the correct weight.
Remove the exhaust side spark plugs, outer timing belt cover, and crankshaft pulley.
Turn the crankshaft until the number one piston is at top dead center (TDC).
CAUTION The camshaft belt tensioner tool (303-097) can be damaged when trying to relieve belt tension if you attempt to remove the belt without first loosening both the timing belt tensioner adjusting bolt and the spring pivot bolt.
Loosen the timing belt spring pivot bolt, but do not remove it at this point in the procedure.
Loosen the adjusting bolt slowly and release the spring tension.
Turn the tensioner with the camshaft belt tensioner tool (303-097), against the spring pressure, clockwise to the farthest position.
While holding it in this position, tighten the adjusting bolt to hold the tensioner away from the belt.
Remove the timing belt.
Be certain that on piston number one, the crankshaft is at TDC with the crankshaft keyway pointing straight up and the circle on the crankshaft sprocket lined up with the notch on the engine front cover.
Line up the timing marks.
Install the timing belt over the crankshaft sprocket going counterclockwise over the oil pump sprocket and over the camshaft sprocket.
Loosen the bolt allowing the tensioner pulley to press against the timing belt.
NOTE: The timing belt tensioner should not be tightened or the belt tension will not be evenly distributed over the whole belt.
Turn the crankshaft two revolutions clockwise. Next, slowly bring the crank to the number one position firing position with the keyway on the crank facing up. The dot on the crankshaft gear is lined up with the notch on the front cover.
Check the timing mark alignment again. If necessary, repeat the procedure.
Tighten the bolts. Torque the pivot bolt to 30-40 ft-lb (40-55 Nm). Torque the adjustment/locking bolt to 26-33 ft-lb (35-45 Nm).
Install the crankshaft pulley and tighten the bolt. Torque to 93-121 ft-lb (125-165 Nm).
Install the outer timing belt cover and tighten the bolt. Torque to 70-106 in-lb (8-12 Nm).
There is something on your scan glass that is blocking the light. If you open your ADF ( where you put the paper in to scan) like you are removing a jam there will be a long piece of glass. If you look at that glass there is probably dirt, ink smear, or whiteout smear on it. Clean that glass and try to copy a page. This should fix your problem.
Hope this helps.
I ran the hp toolbox "cleaning" mode too and it did not help the problem at all. I still have a dark smear concentrated in the middle of the page, and ghost images repeated lighter all the way down the page.
See the manual. It looks as if 120g/m2 is the heaviest paper it can use:
"Set Type to correspond to the paper loaded in the tray from
which you want to print. This will let you get the best quality
printout. If not, print quality may not be acheived as you want.
Thin: Less than 19 lb (70 g/m2) thin paper.
Thick: 24 lb to 32 lb (90~120 g/m2) thick paper.
Cotton: 20 lb to 24 lb (75~90 g/m2) cotton paper such as Gilbert
25 % and Gilbert 100 %.
Plain Paper: Normal plain paper. Select this type if your printer is
monochrome and printing on the 16 lb (60 g/m2) cotton paper.
Recycled: 20 lb to 24 lb (75~90 g/m2) recycled paper.
Color Paper: 20 lb to 24 lb (75~90 g/m2) color-backgrounded
