Hi there, I recently got my platen, worked through the manual.
I got the machine running smoothly (without any ink yet) until the last 50 pages ( normal 80 gsm bond to practise). The feeding table stops lifting. The setting at the feed table lift is set on normal. I tried adjusting the ‘feed table lift’ switch to the cardboard setting, but that helps only for a further 5-10 pages before tripping again. Once I can sort this out, I can finally get my hands dirty with ink. Any suggestions? Help would be greatly appreciated.

maybe lowering your blower will help.
If all attempts are failed , watch the feed table lift pawl during the run ,if you can see it trying to locate in the teeth of the big wheel but jumping over the tooth when you can see it needs to locate, the pawl may be worn , sometimes close inspection of the pawl will show the wear to be obvious ,sometimes you can see metal left where there is no contact and the absence of a distinctive pointed tooth will also give you a clue.
this is easily removed and just run a stick weld along the tip of the tooth you can see quite obviously how it should look ,it literally has a point in profile view ,just grind the weld back to a point and you are away again , you wont be putting much metal back on and the issue of weld to cast is not a problem in this instance ,the amount you will be adding back will likely be around 1 /16 ” you may find that you just need to alter the connecting rod this is no difficult task but often you find they have already been adjusted to the max . Have a good beak around and post back if you have a different view !
Don’t know what effect this would have on your problem, but the rod that connects to the pawl is adjustable. At the bottom of the rod are threads that can be turned out. In effect changing the length of the rod. That changes where the pawl contacts the toothed gear and changes the feed speed on the table. I’ve done this several times and it doesn’t take many turns.
