Olivetti logos 45 dot matrix printer problem
Hello,
I have a couple of Olivetti Logos calculators such as 42PD, 45PD (on the picture) and 75S. These all have a common dot matrix printer of a reliable electro-mechanical design. The only problem that I have encountered is that the platen gets hard and stiff such that the paper is not fed properly - see the picture. The paper runs via the platen and is clamped towards the platen by a relatively small metal counter-wheel that is resiliently biased towards the platen from the underside. The paper now slips between the counter-wheel and the platen. I have tried to rug the platen and the counter-wheel with a fine paper, and have tried to soak the platen with brake fluid that I read could be used for typewriter platens that have gotten stiff. After the brake fluid treatment, the printer worked OK for a while, but after a while it was back to its initial bad paper feed. Anyone has any suggestion how to counteract this problem? Best regards Jonas |
