I had the same issue as well but figured out that some PDF files are sent as type application/octet-stream in FireFox. I don't know why. But try to open mimetype.php add it to the mimetype array of pdf file like this :
'pdf' => array('application/pdf', 'application/x-download', 'application/binary', 'application/octet-stream'),

Remove this line:
$this->load->library('upload');
Then add this line after end of switch block and before foreach block
$this->load->library('upload', $config);
You are loading the upload library and then setting config values, which has no effect.
Your modified function should look like this:
function upload_file($type, $upload_type)
{
//upload file
switch($upload_type){
case "image":
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|jpg|png|pdf';
$config['max_size'] = '3000';
$config['max_width'] = '3224';
$config['max_height'] = '1268';
break;
case "doc":
$config['upload_path'] = './uploads/pages/doc/';
$config['allowed_types'] = 'pdf|doc|docx|xls|ppt';
$config['max_size'] = '3000';
$config['encrypt_name'] = TRUE;
break;
}
$this->load->library('upload', $config);
foreach($_FILES as $key => $value)
{
if( ! empty($value['name']))
{
$this->upload->initialize($config);
if ( ! $this->upload->do_upload($key))
{
$errors = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('flashError', $errors);
}
else
{
$this->page_model->process_file($type, $upload_type);
}
}
}
}

Are you using FireFox? I had the same problem, originated by FF. The mimetype reported is application/binary, so you can chage that in mimes.php
'pdf' => array('application/pdf', 'application/x-download', 'application/binary'),
that should solve the problem.
