In the Optiphot there are two small grub screws under the left hand side of the condenser column. Once loosened the metal housing of the pinion can by pulled or pushed out and the new one inserted. You may need a small mirror to see the screws due to their hidden position. You can then replace the pinion in which the black nylon gear will have broken

C-2257 error code


First check the alignment front and rear of the finisher, check the finisher exit guide rollers if the paper is exiting properly, open both rear and the front cover and check the lower gears attach is the up/down drive belt. that lower gear one might be broken by the pin slot. This code is for a bin/tray raising or lowering failure in the finisher. This can be caused by either the trays not being fully inserted into the finisher or something stropped the bins from raising or lowering. Check the trays and make sure they are as close to the finisher/fully installed as possible. Then turn off then back on the main power switch (NOT the stand by one on the control panel)
You should see the bins raising and lowering into their home position.

I have a 3 1/2 ton floor jack it is a craftman it will lift, but whene i put weight to it it will not lift anything where do you put the oil in to it. thanks gerald


Hi, Gerald -

You either need to top up the oil, or change the oil. Both of these are easy to do.
You'll need some high-grade jack oil, an Allen wrench, a rag or two, and a funnel.

1.) Relieve the pressure and lower the jack arm all the way down.
2.) Remove the tool tray from between the two rear wheels.
3.) Wipe the oil fill plug clean. (You don't want any gunk or debris falling inside.)
4.) Remove the plug with the Allen wrench.

Look inside. If the oil level is at or below the inner cylinder wall, you'll need to add oil. Don't go more than 3/16"-1/4" above the inner cylinder wall.

With the pressure still off, gently raise & lower the arm two or three times. Check and adjust your oil level again. Then screw the plug back in & tighten it with your Allen wrench.

Everything OK? Great. If not, repeat 1 through 4, then lay the jack on its side & drain ALL the oil out (into a container). When it's empty, set it upright & fill it. Again, raise & lower the arm several times.

Replace the plug, tighten it, then test. Raise the jack all the way up, then lower it all the way down, without any load on it. Repeat this two more times. (This helps to dissipate the air bubbles in the oil.) It should now be ready to use.

To Remove:
  1. Before servicing the vehicle, refer to the precautions at the beginning of this section. NOTE: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly (clock spring) to become uncentered, which may cause damage to the assembly.
  2. Lock the steering column by installing the J42640 into the underside of the steering column.
  3. Raise and support the vehicle.
  4. Remove the tires and wheels.
  5. Remove the power steering gear heat shield.
  6. Remove or disconnect the following: CAUTION
    Failure to disconnect the intermediate shaft from the rack and pinion stub shaft can result in damage to the steering gear and/or intermediate shaft. This damage can cause loss of steering control, which could result in personal injury.
    • Intermediate shaft lower pinch bolt and coupling from gear
    • Pressure and return pipes from the gear
    • Electrical connector, if equipped
      Stabilizer shaft links at lower control arms
    • Remove the left stabilizer shaft insulator.
    • Rotate the stabilizer shaft to access steering gear bolts.
    • The outer tie rod retaining nuts.
    • Using J24319-B separate the outer tie rods from the steering knuckles.
    • Rack and pinion attaching bolts
    • Rack and pinion assembly through the left wheel opening.
  7. Transfer the outer tie rods if replacing the power steering gear.
To Install:
  1. Install or connect the following:
    • Rack and pinion assembly through the left wheel opening and tighten the bolts to 70 ft. lbs. (95 Nm)
    • Electrical connector, if equipped
      Pressure and return lines to the steering gear and tighten the fittings to 22 ft. lbs. (30 Nm)
    • Heat shield and bolts. Tighten the bolts to 7 ft. Lbs. (10 N)
    • Install the left stabilizer shaft insulator.
  2. Install stabilizer shaft Links to lower control arms
  3. Intermediate shaft to the steering gear and tighten the pinch bolt to 35 ft. lbs. (47 Nm)

I have a 2008 Triumph Sprint ST 1050. How do you adjust the foot gear change selector ?


There are 2 nuts on the bar from footrest to gear-change, 1 has a right-hand thread & the other has a left-hand thread.
Undo them both then turn the bar to alter its length thereby raising & lowering the gear-change height

Ride safe

2003 grand am-rear window lowers but wont raise-motor working both directions-can raise window by hand-dont know about cable operated-diagrams?


Sounds like the two tabs that connect the window glass to the motor hardware may be broken off. This happened to me before. It will let the window go down because gravity and the weight of the window let it fall but when you try to close the window it is only getting pushed up with either the front or back tab on the window jamming it in the tracks and not letting it go up.

NO paper light


Something worth considering: Check that there is enough slack in the paper tray to allow the gears at the front to lift the paper to the pickup wheel. I've found that on my firm's 8860DN, the paper tray being set too "tight" can cause too much friction, preventing it from moving. If you can raise/lower it by hand (using the gears on the side of the tray), you should be fine.
