Hp HP Color LaserJet 3700DN

HP color laserjet 3700dn has ink but thinks not

Our HP color LaserJet 3700dn is flashing a message "REPLACE BLACK CARTRIDGE" and will no longer print but there is still lots of ink left, it will print a beautifully clear supplies status page. How do we get round this?

How many pages remaining does it show for your black crtridge on the supplies status page? Does it show that the low has been reached?
Also is it a generic cartridge? There have many cases where generics will not give you a low cartridge warning.
The only things you can reset yourself is the fuser and transfer belt count on this printer. The cartridge haves a chip(E Label) that haves your page count,serial number info ect... and this haves to be reset to let the dc controller board of the printer know it haves a new cartridge.You cannot reset the chip yourself.
If you have over 500 pages left for your black cartridge according to the supply status print out I would call whomever you recieved the cartridge from and get a replacement.

Thank you for you reply!

It had got down to 0 pages remaining on the supplies status page and then no more printing no matter how many times you asked!

The cartridge was rather annoyingly the top notch expensive HP variety, and we have just had to replace it in the end, despite the printer still giving us the supply status pages in perfect quality!

I guess we will be losing the last bit of ink every time thanks to the marvellously tight HP chipping system, as if these companies weren't making enough money!

Oh well, we will just have to source cheaper cartridges, at least I know now there is nothing more we can do.

Cheers again,

A source for cheaper HP cartridges.... Buying a referbed or noname cartridge can save you money at the time you buy it.. but cost you money in the long run as they are not as reliable, and if you have a service contract on your printer.. HP would not be happy if they didnt see thier cartridge in there ;) and may even not cover problems resulting from a leaking noname....

I agree with Craig! We are a authorized service provider for HP.We have seen that If you are using non HP supplies and the HP case specialist believes it could be causing your a problem they will request that you get authentic HP supplies. I have seen this alot. In rare circumstances they may void the warranty.I know the HP cartridges are expensive, but because of quality control issues with generic cartridges HP gets a little jumpy when they find out that a customer is using "non-HP"
If you buy a generic make sure you get them from a reputable dealer that stands behind their product!

The fact that you got all the way down to zero pages tells that the printer and toner did their job. While the cartridge may feel full it has reached it maximum output. The weight is probably caused by waste toner (a by-product of the laser printing process). Black toners will have a tendency to fill faster than other colors, both because of its position (it catches some of the other colors waste as well as because of the normal higher usage of black (printer fuctions as a monochrome printer also). The relatively low price of these printers ususally causes sticker shock when its time to replace consumables.

Once a cartridge is installed into a particular 3700 printer it becomes 'married' to it. If the cartridge is then installed into another printer, a question mark '?' will be displayed in the status window for that cartridge and status monitoring is disabled for that cartridge, but it will continue to print.
The quasi solution is to get a cartridge that was used on another machine, or at the very least, just the e-chip. You will get a '?' in the display, but the cartridge will continue to print. When quality degrades, then you know you are really and truly low on toner. Now, you can buy a new genuine HP cartridge and replace the e-chip on the new one with the one that gives you the '?'. You will now continue to print but without the level monitoring feature, just like the >>olde<< days, when the you knew to change cartridges when the print quality became poor.

You do not even have to do that. This printer has a disable cartridge check in the diagnostics menu. Choose it and you can continue to print as it does not monitor the toners. If you only print black you can remove all the color toners and still print in this mode. Good for sacing color toner as when you print in black most hp printers alos use some of the color toners.

But you need to do the disable cartridge check in the diagnostics menu every time you turn the printer on.

Just keep the printer on all the time, plus as I stated above you have the advantage is only printing in black or having a job in black only that is large of removing the color toners to save on them. Most users do not have access or other printer's toners.

Keep the printer on all the time, yeah, right.

Why not! It goes into sleep mode after a long period of inactivity and uses less power then your tv uses when it is off. You end up using more power when turning it on and off since each time you turn it on it has to initialize and recalibrate which uses probably more power then if left on and not in use for over a week.
