I thought of that. The problem occurs ...Ahhh, yeah. I thought of that. The problem occurs even when there's no ribbon. My only guess is that when the ribbon is set to spool to the left, the worm gear is at a pretty straight angle to the tension belt, where it connects and is turned. When it's set to spool to the right, the worm gear drops to engage the gear below, which puts it at a slight angle on the tension belt side. I'm wondering if maybe the knuckle in the worm gear rod (sorry, I don't know all the technical terms :P) has some build up inside that makes the rotation at this slight angle a bit more sticky. It's not a ton, but just enough to stop the carriage from advancing every once and a while (typically at the start and end of a line).<br /><br />If I figure it out, I'll be sure to let you know. Thanks for your thoughts, though!Nom Nom Contributorshttps://www.blogger.com/profile/08169641897491410503noreply@blogger.comtag:blogger.com,1999:blog-1906642113469252066.post-36626386360486586532013-11-15T02:31:35.579+00:002013-11-15T02:31:35.579+00:00This comment has been removed by the author.Nom Nom Contributorshttps://www.blogger.com/profile/08169641897491410503noreply@blogger.comtag:blogger.com,1999:blog-1906642113469252066.post-87122298026657732932013-11-08T09:45:08.125+00:002013-11-08T09:45:08.125+00:00I'm afraid I can't help but a niggling tho...I'm afraid I can't help but a niggling thought tells me that the best way of replicating this might be to wind the ribbons the 'wrong' way round. The KHM threads differently from most machines (though Corona 4s are like this too) in that the feed and take-up sides of the spools are nearest the keyboard rather than the platen. Undue tension in the ribbon may be preventing the carriage from moving. That's probably not it, but worth checking the obvious first.Rob Bowkerhttps://www.blogger.com/profile/12065940710708289511noreply@blogger.comtag:blogger.com,1999:blog-1906642113469252066.post-81665239082098998152013-11-08T05:35:40.655+00:002013-11-08T05:35:40.655+00:00Hello.

I had the same problem with the carriage not advancing on my KHM, but (and here's the kicker) it only happened when the right hand ribbon was engaged. If it was set to engage the left hand ribbon, the carriage moves like a dream! I adjusted the tension like you suggested but it still hangs up on the right hand ribbon setting and now it's just a bit too strong on the left hand ribbon setting. I've tried cleaning the cogs and rods thinking some gunk built up in the worm gear or something, but I can't figure out for the life of me why the issue only exists when the right hand ribbon is engaged. I can work around it, but for a machine with automatic spool reverse, I kind of want it to work.Nom Nom Contributorshttps://www.blogger.com/profile/08169641897491410503noreply@blogger.comtag:blogger.com,1999:blog-1906642113469252066.post-8588199752118779692013-11-08T05:35:22.534+00:002013-11-08T05:35:22.534+00:00Hello.
