How HTML Codes Display on your Browser: Symbols Beyond ASCII

The most reliable way of displaying non-standard characters on web pages is by specifying them in numeric form. For example, − gives the minus sign. The red ones in the table below are deprecated, the green ones are those most essential for proper typography in screen text.

Metrix 51EX

The MX51EX is a quality, French-made digital multimeter rated for hazardous environments such as gas plants and oil refineries. Metrix kindly provided the scanned pages of the manual as a PDF file but unfortunately the file was corrupt. It took some doing, but here is the fixed version.

Scanned (fixed) MX51EX Manual (English pages)

If the blanking plug is removed from the right-most socket, up to 10A can be measured, only the decimal point is in the wrong place. The fuse and circuitry remain from a similar model.




Fuser Grease

A truly arcane topic is the grease used in laser printers. At the fuser, the sleeve rotates around the heating assembly, and the grease required to lubricate the inside of the sleeve must withstand very high temperatures. Some manufacturers, especially of photocopiers, use a constant supply of oil to get round this problem.

The issue is, what grease to use when refurbishing a fuser? Below is a summary.

For older and standard printers, plenty of people are using Chemplex 710, which is silicone based.

If a fuser film sleeve has a metal contact ring at one end, it requires fluorinated polymer grease. “The metal base sleeves are built for newer models of printer, such as HP LaserJet P4014, HP LaserJet Enterprise M601, HP LaserJet 4250, HP LaserJet 4300, and most color printers such as HP Color LaserJet 4700, HP Color LaserJet CP2025, HP Color LaserJet CP3525 etc.”

“My supplier told me that Canon/HP uses the Uniflor grease on their fusers at the factory. They claim they contacted HP with a fake grease in the eye claim and asked for the MSDS which pointed at Uniflor as the supplier. The grease won’t stay liquid as the heat will solidify it. If you ever took apart an OEM fuser that had 200,000 copies on it, you’d see that grease had solidified as well. We haven’t experienced the failures you’re having. Maybe some of the other forum techs will voice their opinion. - moe”
