Need to open housing to clean bottom plate

Looks like we had a bad ink cartridge that leaked in machine. We cleaned rollers and area that's accesible from the front of the machine. It looks like some of the ink has found it's way below the rollers/cartridge on the housing floor/plate and mixed with dust which the rollers continually pick up and I'm getting faxes with light/gray lines that can't be read. I need to open the housing to be able to clean the bottom plate and get all the ink residue out. I don't see any screws on the bottom plate that I can loosen to remove upper from lower housing. There are 2 openings with tabs (that may have to be pushed to sides to release?). I only see 6 exterior screws (2 lower front housing; 2 upper housing under key pad and 2 in the back on either side. and 2 small screws accessible from the front that look to connect front housing. Any suggestions. Thanks Hank

    Thanks newtekkie for your prompt response to my problem. I took off all 6 visible screws. The bottom plate now gives a little (@ 1/8 ") in the front when I place a flat screw driver and attempt to pry off. Still not enough to get in there with a towel to clean up. There is still something holding it closed. I'm thinking the 2 small tabs on the bottom/each side. They look like metal tabs in a recessed plastic opening. Although they give a little/move from side to side when I pry them with a small screw driverI, they don't give enough and looks like they are what is keeping the bottom plate attached to the upper housing. Don't want to pry too hard and brake the plastic housing and then I won't be able to close it/secure the bottom plate back up when I'm finished cleaning. Any ideas on these tabs??

Unscrew the housing screws. Take a piece of paper towel saturated with denatured alcohol and twist the towel, blot up ink

    Yeah, I would hate for you to accidently break the equipment trying to open it. Have you ever opened the fax machine before? Are you sure you might have to lift the tabs.

I have just replaced all the toner cartridges in my fax and it did a self clean. The machine was making these noises which sounded like the roller was getting stuck. It would then come up with a paper...

Open control panel on your personal computer where the printer is installed. Click the printer and faxes. Then right click on the icon of your printer and click properties. Then click the maintenance Click the Bottom Plate Cleaning. If the noise is still there after you clean the bottom Plate. Clean the Roller. And look inside your printer if there is something that blocking the roller.

Canon Pixma MP800 Prints a 1/4" black stripe on back of page. Is emptying the large PGI-5 cartridge in record time. Have replaced cartridge, run cleaning and maintenance routines. Cleaned bottom...

I have seen this before but it has not caused the black to run out quickly. if you look into the machine you will see at one end of the platen roller it will be swimming in ink. As the paper passes over the roller it will deposit ink to the back of the paper. now why is the ink getting there? Well its just possible that air hole in the cartridge is blocked but you say you have replaced the cartridge. Ah but with what? are you using recycled cartridges? they may be filled with ink and not dye which is what originals use. Dye is much thicker than ink and ink maybe leaking from the cartridge. The seal in the carriage may not be making a clean contact with the base of the black cartridge causing it to leak when the carriage is moving. Check those out and repost if still having the problem.
Good luck

I have an HP C6180 printer that seems to be leaking ink inside the printer. I had not used the printer for a month or so whilst I was moving house, and changed all the cartridges as most of them were...

You could carefully clean this as follows:
put the printer on some newspaper to avoid further spills.
Turn on the printer, then open the lid to allow the carriage to move to the center.
Now unplug the printer, then gently move the carriage to the left and out of the way.
You should now have limited access to the spittoon area.
You can clean this area by carefully scooping out the ***** of ink with a plastic spoon. (Be careful not to drop ink sludge on your printer, desk, carpet or clothing.)
Once most of the ink has been removed then use a crumpled paper towel to soak up the ink in the bottom of the service station.
It may take several rounds of this to clean up the service station.
It is not necessary to completely clean the service station, just get the majority of the ink out.
Once this has been completed you could turn the printer up and clean the bottom area of the printer. Do not tip up the printer before the service station has been cleaned or you are likely to create a mess....

Suction from base limited but not from handle.


This is a difficult repair to try and guess what may be the problem, but I will try and go over a few things that may be wrong with your vacuum.

1. Filters. You should check the filter that is in the top part of the dust bin first. This is the circular blue filter that should be washed every 3 months. Once yo have the dust bin out of the vacuum cleaner, you can see the latch that opens the filter housing in the front of the machine where the handle comes down. Simply open up this latch, and check the filter underneath. Is it visibly dirty? If you've recently washed this filter, and it appears clean, then you don't really need to wash it again, this is probably not the problem. If you haven't washed it lately, or if it appears dirty, just rinse it off with hot water, and make 100% absolute certain the filter is dry before re-installing it into the vacuum.

2. Brushes on roller brush. If the filter is ok, check the brush roller, and specifically the length of the bristles on this roller brush. Even though brand new, the Dyson roller brush doesn't have very thick bristles, you should be able to see a small part of the brush protruding through the bottom sole plate. How long are the brushes? I've posted a picture below of what a new one looks like so you may compare them. If the brushes are low, then this maybe a reason why the machine is not picking up well on floors. The average life of a Dyson roller appears to be about 3-4 years only. If you have to replace it, there's an even better roller brush that's a generic part that has longer, and thicker brushes, for much less then the genuine Dyson part. Here's the picture;

3. Bottom Sole Plate. Sometimes we see from customers Dyson models when they bring them into Govacuum for repair that at some point the bottom sole plate had been removed to clean the brush roller. Some of the times when the customer re-installs the plate, the plate is not installed properly, and it's a good .5-1" higher off the carpeting then it should be. If you've recently cleaned your roller brush, check on the both sides of your vacuum. Particularly where the bottom, grey colored part meets the purple colored part that the roller brush is housed, also known as an brush roll housing. The grey colored part should be flush completely with the purple part on the sides of the vacuum. Do you see any cracks on either side in this particular area? If yes, then remove the bottom soleplate, and reinstall it properly to ensure that the plate meets the agitator housing flush, with no space. I can't tell you how common this problem is, we see it very frequently.

4. Internal Hose. While you have the machine upside down to inspect the soleplate, check the internal hose that connects the purple agitator housing with the motor area of the vacuum. Sometimes the flexible hose will stretch, and finally crack, usually right at the end of the hose before the rubber hose cuff that connects into the agitator housing. Can you see any visible damage here? This is a picture of what this hose looks like;


If none of these suggestions have fixed the problem, it may be something more serious. If you'd like, I can try and further diagnosis your problem here on Fixya. Please just use the clarification request, or post a new comment on this page, and let me know some further details of what happened after trying this suggestions. If one of these did fix your vacuum, great! I'm glad this helped you. If this was helpful to you, please be sure to rate the repair by clicking the thumbs up icon at the top of the repair.

Thank you very much,

I have cleaned and deep cleaned my canon mp520 and roller cleaned and bottom plate cleaned and STILL I am getting black ink blots and smudges on newly printed pages. HELP??!!

I would try manually cleaning the cartridge. Please see my tip on doing this.

I believe that the area that the printer uses to clean and cap the heads can become soaked with ink. You may have already cleaned this area but if not I would do it. It's a sponge surrounded by a gasket that is used to clean the cartridge and to cover it when not in use so that the ink doesn't dry up.

If this fails, I would replace the cartridge(s) and see if you still have the same problem.

Hope this helps and good luck!

Same Problem - Wet Black Line on back of each printed page

Print cartridge

When the print cartridge contacts are dirty and the printer cannot detect/communicate with print cartridge.

Clean the contact points on the cartridges with a dry, lint-free cloth.

1. Open the top cover of the printer.

2. Remove the print cartridges.

3. Clean the copper-colored contact points on the cartridges with a damp, lint-free cloth.
Use a dry, lint-free cloth to remove moisture from the contacts.

5. Insert the cartridges back into the printer.

6. Close the top cover.

7. Try printing again.

If you still cant communicate try with new cartridge .

Hope this help. Please Rate My Response! Thanks!

To solve the printing problem..

# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.

1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

# Reinstall the cartridges, making sure you snap them correctly into the printer.

How can I get the fax and copy to print clearly?

Still sounds like a bad ink cartridge, try cleaning the bottom of the cartridge with a Kleenex and soapy water. Dry it off real good.

Look where the cartridge sits and clean the same way.

Ink jets are dead technology.

Leaking ink

There could be two problems.
1. Left over ink. Requires a complete printer cleaning from the inside. You will have to open it up and clean it.
2. If you have replaced the cartridges and still the problem persists, it means that the print head needs to be changed. It is malfunctioning and thus allowing more flow of ink from the nozzles.
