That double keypad circuit at 6:30 can be also there so you can still use it as a phone, when there's no power in the building. You won't see what you are typing, but I guess it still sends the DTMF signals and you get a connection.
First thing that popped into my head - hook it up to a gryo/accelerometer, basically so it can be located in space and know its rotation, then use the addressable elements to draw a large image on a large sheet (or multiple strips) of paper. Would look pretty cool if you could just pass the thermal strip over a sheet of paper and have to draw things.
The thermal head could be used to keep it at a nice temperature in case you are using it when it is very cold like 3 degrees so it doesn't damage the printer from frost or frost up the mirrors.
It has nothing to do with over engineering or phone voltages, isolation or world standards but it allowed the phone part to be used in emergencies in the case of a power failure, as the phone section is powered from the telephone line and not the fax machines power supply.
I believe the cam operated micro-switch is used to inform the CPU of a paper jam. (I'm sure someone told me this years ago) Stepper motors are indeed very accurate, However it may be cheaper to have a micro-switch detect if paper is still moving than using some current sensing components just before the stepper motor. I do have an old fax machine I could test this theory on later (It's somewhere in the attic), I will comment if disabling the switch in mine reports a paper jam.
@@a531016 Sorry for the long delay, Mine don't have a cam operated micro-switch but does have an IR source & detector component reading from a wheel with a small slot in it that is directly connected via gears to the stepper motor. And sure enough if I block the sensor it reports a paper jam. Although mine is done with a different component it does seem very similar in its design. Also spoke to the guy who told me (Thanks Jason) and he said it's also very common in laser & thermal printers.
A video I never thought I’d need to watch. The first thing I ever took apart was an old fax machine. Beige and heavy. I kept the circuit boards and mechanical parts in a box for half my life.

Hi, phone fax Sharp FO-85. When dialing a phone number, there are constant beeps and there is no connection. In the manual in the malfunction section there is no description of such a situation. What is the reason? Thanks
I think the last time I used a fax machine was 10 years ago when I was buying my home. I seem to recall that early spacecraft sent back pictures as Fax.

@@a531016 if find it quicker and easier than scanning + sending an email, but less flexible. Also the company kept it so they could work in case of an internet problem
Yes an interesting video ! We used a fax machine that we used as a document scanner with a PC - no public phone line was used. In those days, apart from fax machines, we had dial-up modems. The modem would be connected to the computer by a serial port ( which also no longer are a regular feature ) Supposing we wanted to scan a sheet of paper into the computer. The phone leads from the modem and the fax machine could be connected together in their own "special" circuit.. A DC offset current was required to make them talk to each other, so between the positive and negative leads of that phone circuit, a PP3 battery and a resistor ( few hundred ohms ) was wired to provide the current. The paper was loaded into the fax machine. The modem and fax were put into operation, and the sheet of paper would be scanned in to whatever fax application was running on the PC. The phone connection was not, of course, IN ANY WAY connected to any public telephone system - it was completely separate. Nowadays of course most printers have built-in scanners, and mobile phones can scan in documents. Panasonic fax machines were good unless they were struck by lightning - then Panasonic wanted "big money" to repair them...
I have never heard of that arrangement before, that's kind of like a twister ethernet cable but phone line based instead? That's super really interesting, I with I had enough hardware to try it!
Hi our phone leads in UK are four-wire flexible. The modem and fax were both put across positive and negative, along with the battery and resistor that were in parallel with each other ( the resistor was a current limiting device in that case.) The PC was put in receive using WinFax. Send was pressed on the fax machine. Worked well once you became used to the procedure. Unplug battery at end of it goes flat!
I have a question. I want to recycle my old 1993 Panasonic Personal Fax machine KX-F550). I read that I should remove the memory to avoid ID theft. Can you tell me what I should remove & where it is? I am not an expert in this. Thank you
mike brown, not true. I worked for Panasonic from the start of 1980 through the fax revolution, until 2012. If companies had 2 or more fax machines it was due to efficiency rather than compatibility as every fax machine had to comply to the international facsimile standard. I directly worked with technical and software engineers in Japan and yes, there were sometimes issues between brands but they were always resolved quickly with firmware upgrades. Facsimile sales were a huge part of a sales companies revenue back in those days and compatibility issues were extremely important.
@@brucea5664 the factory might have been making firmware modifications for future production runs, but virtually no one in the field was getting them, unless they were shipping them back to the company.

Walmart has a good thermal paper scam going, when you buy a car battery it has a 24 month replacement period... trick is you need the original receipt which is printed on thermal paper. After 6 to 8 months (at least in my experience) it reverts back to a plain sheet of paper and you can't tell what was printed on it... so they don't have to warranty it because you don't have proof of purchase.

I'm currently taking apart a atleast a 15 year old facsimile by Sharp Corp. And the things inside are amazing.. (granted I'm only 23, so this is like finding a dinosaur lol) at least I know what A tracks and a VCR is
Why would someone choose to use a dc motor in a precise device rather than using a stepper motor to be as precise as possible? Not to mention having to replace brushes and adding more space for a fancy controller. The stepper motor would work efficiently and precisely the entire time and is easy to run. I used the stepper motor from a fax/printer to win 1st place at a chemE car competition. While everyone else was rushing to get across the finish line and running out of chemicals for their reactions, my car was slowly chugging along with a very low concentration of chemicals that worked exactly how it was supposed to. I apologize for rambling that’s just one of my favorite school stories.
Rabmling always welcome - well done on winning I guess! What controller did you use for the motor? I think that may be the big decision in a lot of places, if there is enough IO for the Stepper and the cost of the controller?
Thermal printing was much superior than inkjet for fax machines in the early days. Inkjet could not achieve the resolution required for printing Japanese characters accurately so virtually all fax machines in Japan were thermal.
David Edwards fax resolution kept improving but strangely inkjet never really took off in Japan until the resolution was at least 600 dpi. Copy and printing resolutions were similar because the Copy (Photo Copier) function was quite popular, later fax machines could also be used as a PC printer (usually just inkjet or toner)

Inside a 90s fax machine: Scanner, telephone circuitry, elaborate analog processing circuitry, hardware compression script, modem, thermal printer, processor, backup battery, RAM chips, ROM chips
