What film? Where from?

This is a known fault with this retro model, I'm afraid - over time, the plastic gears get worn, and eventually fail. Solutions are mentioned on the Pentax Forums.

Repair would be at least $139 from Blue Moon Camera. I would buy another MZ-50 (ZX-50 is the same) off eBay or you could buy a ZX-30 from Blue Moon Camera for $75 with 1 year warranty. They are professional.

Pull up on the rewind knob ( left side ) to open the film door. put film cassette in chamber then lower rewind knob and pull enough film leader to the take up spool. attach film to spool. close the film door then advance the film to #1 on the counter.

Hey sorry i dont have an answer but i have the same camera can you help me?

I used to use point and shoot film cameras. My guess is that there is a button underneath which when you depress will automatically rewind the film. Sometimes the button is very small that you may need a ballpen point to press it. Hope this helps cuz i have no idea what the Pentax Zoom looks like. I am guess it is a point an shoot type and not an SLR. If it is a point and shoot type, you must be sure the battery has power or else it won't rewind.

The Pentax MV has a similar body and uses the same lenses as the Pentax ME Super, but it is a fully "Auto Exposure" camera. It does not have manual override or shutter-priority modes. It is a good camera to take pictures, but not if you want to have full manual / creative control over the camera.

Take care & Happy Imaging!

Others here have suggested the problem lays with the plastic gear on the advancing motor beside the mirror.

This might cost $100 or so...?

Could you be putting too much film onto the wind spool? Take the end of the film leader no farther than the RED/ORANGE marker at the spool. Too much film will cause it to bind and start rewinding.

I wish i could help you, but Pentax's manual is poor and many people (over the net) face Pentax error message with no meaning... i would take it to your local camera repair shop. If they can't help you call ProCamera in harlottesvile VA. He collects pentax owns his own shop. He's been in business for 12yr's he is also a succesful photoghrapher. I''ve heard nothing but the best about this guy Bill Moretz. I have a pentax if anything happens to hit i know where i shipping it of too and pentax is the only camera i will own. His prices are right so the shipping cosr is worth it.

The IQ Zoom cameras are designed to display error codes (E0, E2, E9, E10, E1A, E37, E90, HL, H4, H5, etc.) when something goes wrong internally with one of the mechanisms or electronic components. These diagnostic displays help to determine where the problem is. When you see an error code, ask a qualified PENTAX repair technician to examine the camera. For information on a specific error code, call Pentax customer service department toll-free at 1-800-877-0155, Monday-Friday 7:30am-4:30pm, Mountain Standard Time.
