OUR MACHINE WORKED GOOD WITH OUR PICKS BUT WHEN WE REORDERED THE MACHINE WILL NOT FEED THE PICS. WHAT DO WE NEED TO DO?

Remove the needle plate and clean the feed dogs with a brush...remove any lint and bits of thread.
A couple of drops of sewing machine oil might help to loosen the feed dogs up. (maybe let the oil seep in and then turn the handwheel towards yourself to help things along.
One other thought:
If your machine has feed dog lowering capability you might want to move that lever/switch back and forth a couple of times.
The feed dogs might not appear to raise or lower, but some machines will only re-engage raised feed dogs when the machine starts to stitch.

Also...verify that the presser foot tension isn't too strong/heavy...and temporarily try using a longer stitch length setting.

You don't mention the brand and model of your machine. If it is 25 years old, it's probably a mechanical machine (ie, not computerized). If it is mechanical and it has not been cleaned and oiled for quite some time, the old oil has most likely gotten sticky over the years. Sounds like the feed dogs are stuck.

Consult your owner's manual and determine that the feed dogs are not in the darning position. Then find the maintenance section on how and where to oil your machine. Most mechanical machines have oil ports (little holes) where oil needs to be applied. Use good quality sewing machine oil (not 3-in-1, WD-40, or cooking oil) or you can pick up a bottle of liquid Tri-Flow Synthetic Oil at the hardware store. Apply one to two drops each spot. To help it along, you can direct hot air from a handheld hairdryer into the internal metal mechanics, focus on the feed dog area since that's where most of the problem is. Sometimes the oil and heat will help free up the old gunky oil. Gently rock the handwheel to get the oil worked in. You may have to perform the process more than once to get it all working again.

All pharmacies used to make you call in your prescription but this is rapidly changing. Today, many pharmacies are willing to reorder for you, which saves all those push button phone calls. When you pick up your prescription, ask the pharmacist if you can sign up for automatic refills.

You have forced the machine out of timing ! You need to either take it to a sewing machine engineer or look up how to adjust the feed timing on you tube ! Good luck

I need a bit more information. Was the machine working correctly before this happened? Have you checked that the threading sequence is correct and nothing is blocking the path? Is the bobbin seated and threaded correctly? Are the feed dogs clear of fluff?

Have you tried to clean the pick up rollers with a rag with a small amout of WD-40 or Simple Green. Clean the roller then whip off with a dry rag. If the problem improves you need to replace the pick up rollers. If not you may have to replace the paper feed clutch. Also, look to see if the seperation pad is ingaging when the paper tray is pushed in. Open the left side door. I've seen the actuator break. Also, have you tried to use the manual feed tray???? I know you made sure the paper guides in the paper tray are set correctly for the size paper in the tray??? Good Luck

Have you replaced the paper pick up & paper feed & paper sep. rollers? Also, have you cleaned the paper pick up clutch? The reason it works with the manual feed is that it is not used as much. Also, have you cleaned the rollers with wd-40 or simple green and did it work better, if so you need new rollers. Good Luck

just check to see if there is any obstructions were the paper is going through, unplug printer cables, press power button for 20 seconds without any cables connected, it will refresh printer memory, connect cables back,try photocopy, if nogo, printer fualty

Brass screw is probably the chrome packing screw which normally sets in a hole near the front of the copier when you open the "**** shell" Paper pick up could need feed wheel. clean with fantastic or soap and water and see if it helps. Also on this model check your exposure lamp is it coming on, if not it may on flicker, On all these PC when the lamp goes bad the paper jams usually at turnaround. Good luck.

Yep the paper feed roller wears and will need replacement (open front cover in centre of machine tabs on either side it just clicks out.

should also change sep pad (multi feeds)
