Never did get zapped by it, which is probably a good thing. I used to work as a computer maintenance engineer very early in my career and I had to fix a lot of commercial grade printers laser and solid ink. The fuser unit that you removed has two main rollers. One is driven by the gear and has a soft gripping surface. The fuser film sleeve has issues and needs to be periodicity replaced. A part of the replacement procedure is to place lubricant between the fixed roller and the film sleeve.
There should be an indicator in the service menu to tell you how many prints the fuser has done and the manual will have a specified replacement interval.
The temperatures were probably played with by the service person that last looked at it. Different toners non-genuine are very sensitive to temperature so use some genuine toner and default the temp. There seems to be another problem with the exit rollers if they are driven rollers. In you video you can see some of the stop rotating while other continue.
If your happy with fixing the bent shaft and your happy that the exit rollers are ok then you can get an exchange reconditioned fuser and just drop it in. Before you jump into buying things have a good look through the service menu so that you can seen how many prints the consumable parts have done as that will give a good idea of what future maintenance costs will be.
The image unit is normally the more expensive part. Thankfully for the world of printing, Xerox was convinced to release the Laser Printer rather than the inferior TV screen product that had been rejected as an option by Gary years before.
Just got an old canon copier. It is ghosting the image about 4 inches to the left on every copy. Any idea what it should be? If the image drum is actually that small then the corona wire is dirty or corona voltage is too low. The corona wire or plate is often removable and there is often a little brush clipped to the internals of the machine that you use to clean it of.
The menu will have lots of settings and these need to be close to correct or problems like this will occur, especially with cheap toner.
The two settings that can effect the problem you describe are the image transfer voltages and the fuser temperature. I hope that helps. I would at least need a model number. You may find some sort of a dent on it exactly 4 inches to the left. Also make sure you clean the copier interior of dust and debris. Worst case scenario — bad drum or fuser unit. One of your problems is what you were copying. If you use a thick paper setting it would slow the whole process and heat up more which may also help you out.
The office where I worked had this exact same model of copier for 10 years; I was the lucky sucker that had to keep the thing working. The problem with yours is most likely that the lid was open when you scanned the item to copy… this model of copier has specific vulnerability to jamming in that situation when it ages. An open lid scan means a dark background on your print, which dumps a lot more toner on the page than normal document copying does.
The extra toner changes the stickiness of the page when it enters the fuser, which causes the page to hang up and get jammed. This model of copier usually has a print sever that you can set up in the Tools menu.
If you decide to gut it for parts and give the empty husk a Tibetan Sky Burial, you can run the toner cartridge dry printing out all of your favorite datasheets first. Dig around the internal components — a lot of these type printers have a hard drive that store copies of everything scanned — look for confidential documents. It was throwing hard drive errors so I actually formatted it! I think it was empty anyway but interesting idea for sure. The question no one asked was did you try fresh paper and run it against the ply.
Damp paper or cheep paper will jam like that all day. I would start by cleaning the contact thermistor s in the fuser. Thanks for commenting! I was hoping I would run into someone with your experience. I did use fresh paper but perhaps the copier was a tad moist inside from sitting outside for several days.
This SP selects the number of pages made at this temperature. See Detailed Section Descriptions — Fusing for more details. This SP selects the length of time that this temperature is used.
That is totally awesome, I cannot wait to see what you come up with. I love finding FREE tech that people just dump because it is old and not because it stops working. Some others already have suggested replacing the rubber rollers, and I second this. I have a Samsung ML laser printer that I have been using since about After two graduate theses, many job applications and numerous other print jobs, the little rubber cam finger that grabs the paper from the tray had worn down.
Very fine Emery paper is best for paper pick-up, paper separator, and pressure rollers especially in the fuser or just buy replacements. They get glossed or glazed and the surface has to be roughed up so that they grip again. I saw a tetrahedral grinder that would make polished stone spheres made from four motors taken from photocopiers. The motors were preferred because of the low revolutions per minute they run well at. So, sabotage a device to make money?
Not sure, what the use, benefit or any other gain of your suggestion should be. Do you find it funny, to annoy people, you do not even know future users of the device?
I mean, the funniest part of a prank is watching the victims, which is not possible in your scenario. I scored a smaller desktop copy machine a couple years back. Completely stripped it down to its guts. Managed to salvage a lot of great parts, including a bunch of stepper motors, linear rails, belts, gears, and spring hinges.
You could likely make a 3D printer with the guts and have a lot of goodies left over. A Ricoh salesperson has been trying to sell the museum a new unit because Ricoh no longer makes replacement parts for the current unit. Many years ago brought a large copier home for my son age about 10 to dismantle, expecting it would take him a few days during school holidays, Unfortunately with access to a drill and driver attachment it only took him 2 hours — lots of parts for the parts box though.
Thanks for the heads up [RoGeorge]. I will be keeping an eye out for these and possibly other high end HP laser printers. This is a very pleasant surprise, thank you! I would put it to work once you get it to reliably boot up.
Check the power supply capacitors. Very helpful when photocopying large items or montages of collected items. Place it in a common area and collect the money. Lewin Day — You have a whole lot of good suggestions here. Your paper stock will not react well in humid conditions. Then under cut them severely. Tell your blokes to spread it word of mouth. Or just charge flat rates. To hold down paper jams do like the others told you. Warm water after Emory cloth and drying is fine before replacement is needed.
Also you will need a paper jam knife-like tool to clear paper dust and small fragments. I have heard that you can clean a cooled fuser roller with Fedron very strong solvent. But I have seen using folded paper, pencil eraser, or alcohol to clean them. Break them and you have a Ricoh service call. Try not to scratch the drum! I have seen copier techs use nail polish to fix drums but it leaves a white-space on the paper image.
Your error code is not severe. You can just clear that like you already have. Also just re-seat the connector, that may fix it. You can break the platen glass and get glass stuck in your arse! Emergency room at hospital? Then you have a much lighter and smaller footprint for moving.
Then get a U-Haul trailer in Melbourne for long distances. If you want to do screenshots of your phone or tablet you will have to turn off or block the the halogen lamp. But that will generate an error code if you unplug it or cause a fire if you block a live halogen lamp.
The lamp is reflecting off of your phone screen so the reflected image is washed out. Never operate the copier with the lid up. Not only does that generate more toner it can cause eye cataracts cook your eyes over time if you look at it too much. Extra toner in image can cause more paper jams too. When cleaning interior use a vacuum cleaner with a HEPA filter. You need an anti-static cleaning spray if you want the ADF to work correctly. Get a thin gooseneck hose for the vac to allow you to get into small spaces and not ding the drum.
One setting can affect other settings. So leave it to a professional if you want it to work correctly. Some things you can use a photocopier for: 1. Printed circuit board templates on transparencies. Make make paper banners 8. Multiple letters or numbers per run. Then choose which character tile you need. Make direction arrows to point someone on a path in your house or flat.
Make transparency overlays for TV, tablet, maps, etc. Any new technology, from the moment it is introduced to the general public, is vulnerable to manipulation and hacking by malicious users. A good example of this is RFID tags in At the time, RFID technology had spread like wildfire across many sectors — tech companies, hospitals, and more were using khz cards to access door secured with electric locks.
Since these ICs had no encryption or authentication, they would broadcast their information as soon as a reader was nearby. This posed a huge security risk to companies dealing with sensitive information and products. Essentially, anyone with the right equipment could steal or replicate these cards and fobs, whether they were authorized or not.
Starting a new project? Learn everything you need in this downloadable guide. A reader, like the one seen here, can easily copy the ID of an existing khz EM, or a similar type of protocol chip, and copy it to another card or fob. One of the first people to attack this security standard, in , was Francis Brown —managing partner at the security firm, Bishop Fox. It's now been five years since Brown developed his tool to hack into these systems and plenty of companies have switched to a more secure, higher frequency standard; however, there are still many businesses that have not updated and still use the khz EM cards and fobs, which makes them very vulnerable to attacks.
Since the frequency is significantly higher, compared to the KHz version, the amount of bits that can be sent per second is significantly higher. That means the data on the chip to be encrypted will be greater, rendering it more secure. Now that encryption is available for these cards, the way they communicate with a reader device is to send out a signal and the reader reads it.
Unlike before, however, it no longer advertises all of its data; instead, it only broadcasts data that is public—like its ID and name. To access sensitive information, you have to provide that sector of memory with the right key—otherwise, it will show up blank.
Even though these cards are a lot more secure, once you know the encryption algorithm you can decrypt them and access the sensitive information. Jump to:. Can a Printer Be Hacked? Printer Security Tips. Printers, an often overlooked aspect of a business' security infrastructure, can be subject to breaches. While many businesses think to secure other aspects of their network, such as firewalls and computers, they sometimes overlook the role that printers play in a holistic cyber security approach.
Hackers knowingly take advantage of this security gap to exploit a business' printers for malicious purposes. Both older and newer printers alike have various security gaps that cyber criminals can exploit.
When your printer is hacked, the following can happen:. There are a few telltale signs that your printer has been hacked:. If you recognize these signs, immediately shut off your printer and contact any necessary IT staff, whether than is an in-house IT department or a third-party IT services provider. Older machines are less secure, which leaves a host of potential issues for your company.
For instance, on older copiers and printers, the connection between a computer and the machines isn't very secure , which means that hackers can more easily access your information when it's sent over your network. For older copiers and printers with less security, hackers who physically visit your office can simply plug a malware-loaded flash drive into one of your copiers or printers, infect the machine, and then infect a company's entire network.
While the odds of this happening are low, the situation is technically possible. This same scenario can potentially play out on newer machines too if you enable features that let you access documents stored on your copiers and printers from your computer.
These hard drives are unsecured, which means a hacker can hack the copier, access these documents, and then access your network. When setting up your copiers and printers, disable this feature if you can. Personal copiers and printers, especially older models, used in managers' offices come with a host of security risks. Since these machines are usually intended for home use, security isn't as much of a priority when brands build them.
