I made a living working on those. At least the 230 had a function to tell you if the phone line priority was reversed, unlike the 220. If it was wrong, they would receive, but not dial out to send.

Remember the 350, and the power supply caps (I think there were 6) that blew from heat, and there was a kit that included higher temp ones?

I believe those Canon Faxs were the some of the first fax machine with ECM (error correction mode) , Huffman Encoded transmission ,"256 shades" of grey scale, using matrix A-D algorithms transmitted over 9600baud.... Wow were they fast for their day.

Nah!, that k-clank sound was fine. The sinking feeling along with the next sound was the worst one.

I don't remember the model number, but Toshiba had a 50ppm copier that used a "pre-scratched" selenium drum. It had a pattern etched into it, and if it wore smooth or you tried to polish it, you lost all copy quality. Lanier used the same print engine for a while. Those old Toshiba BD engines would throw so much toner on the image, you could feel it, almost like braille, but they couldn't do a gray scale no matter how many adjustments you made.

Speaking of damage to drums, anyone else ever use clear nail polish to put on a knick on a drum? Back in the day, not now most are just cheap enough to replace

How about the first time you saw a Sharp "Pre"-scratched selenium drum, think for the SF-9300? The drum was like $500 and when I opened box it had scratches all over it, called my supplier and he laughed his ass off and told me it was supposed to have scratches on it!


Added this after: Ha-ha, right after I posted this I see someone else just mentioned the scratched drum

From what I remember there was a greater threat from the polishing compound than there was from the selenium.

Yep, always nicked one from the wife to keep in the tool bag. Also used nail polish to paint the inside of corona end blocks to give them another layer of insulation to try to stop them burning out so often.

Better to have a small clear patch on the text than a black spot..
Never was patient enough to wait for it to dry.

For me, the nail polish fix only worked on machines without a drum cleaner blade like the Mita DC-121/122, Mita DC-131/132/133R. You could never really get it smooth enough to get good blade contact. You always ended up with a small teardrop shape of toner with a white center. =^..^=

Oh yea how did I forget using nail polish for the corona end blocks. Corona aching was very common. Also insulate inside blocks with black tape. Man all these trade secrets being revealed, too bad 99% of them can't be used today

I started a forum years ago in a effort to bring together all those tricks-of-the-trade.

When I first started the company I worked for was a full line office equipment dealer. We had one tech who worked primarily on mechanical adding machines, Olivetti mechanical calculators and Olivetti and Sundstrand mechanical posting machines. He also kept a pair of shears very close at hand. If your tie got caught in the moving mechanism you got pulled down the machine in about 2 seconds.

Re. Business Tie.
It was such fun when you dragged your Tie through the top filler contain on the old Toshiba BD4505-15, BD3701...
Such fun cleaning your Tie after it dragged toner all over the platen top and down your clean shirt.

The Tech staff manage to protest to the company and get the dangling company Tie remove from Technicians standard work cloths.
The sales department still had to wear them. More often when they only felt like it though....

SCM used to have a high speed electrostatic, coated paper, machine used used strobe lights for exposure. Built on the same self standing frame as the Coronastat 55, the paper never stopped at the registration switch. Instead it flashed a set of I believe 4 high wattage strobe lamps. The lamps used a power pack that could deliver a high enough voltage at a current that could be lethal. I had to replace one once. There was a set of jumper plugs that came with the new power pack that had to be installed on the old one before disconnecting anything.
